| NDT Inspection Report: What to Record From Examination to Final Result |
An NDT inspection is not complete when the technician finishes scanning, viewing a film, checking an indication, or examining a weld.
The inspection must also be properly recorded.
An NDT inspection report is the permanent record of what was inspected, how it was inspected, what equipment and procedure were used, what indications were found, and how the results were evaluated.
For an NDT technician, a report may look like a simple form that needs to be filled out at the end of the job. In professional inspection work, however, the report is much more important than that.
A well-prepared NDT report provides traceability, technical evidence, accountability, and a record that can be reviewed later.
ASNT notes that an NDT report is a reflection of the inspection performed by the technician and emphasizes recording enough information about the technique, applicable codes/specifications, equipment, calibration, and results to make the inspection understandable and traceable.
This guide explains what an NDT inspection report is, what information should normally be included, how to record weld inspection results, what equipment and calibration information should be documented, and how to avoid common reporting mistakes.
Important: There is no single universal NDT report format for every project. The exact report requirements depend on the applicable code, standard, specification, approved procedure, client requirements, and employer quality system.
1. What Is an NDT Inspection Report?
An NDT inspection report is a documented record of an examination performed using a nondestructive testing method.
Depending on the method, the report may document:
Component identification
Weld identification
Material information
Examination method
Examination procedure
Examination extent
Equipment
Calibration or verification
Personnel
Examination conditions
Indications found
Location and size of indications
Evaluation
Acceptance criteria
Final result
Inspector identification
Date of examination
The report should allow another qualified person to understand what was examined and how the result was obtained.
A useful way to think about an NDT report is:
Inspection performed → Evidence recorded → Result evaluated → Decision documented
Without proper documentation, even a technically correct inspection can become difficult to verify later.
2. Why Is an NDT Report Important?
NDT reports are important because inspection results may need to be reviewed long after the original examination.
For example, imagine a pressure-vessel weld inspected several years ago.
A client may later ask:
Which weld was examined?
Who performed the examination?
Which NDT method was used?
What procedure was followed?
Which equipment was used?
Was the equipment properly calibrated or verified?
What was the examination extent?
Was an indication detected?
What acceptance criteria were applied?
Was the weld accepted or rejected?
A properly completed report can answer these questions.
ASNT describes NDT reports as records that may be retained for the life of the inspected product, which is one reason accurate reporting and traceability are so important.
3. NDT Report vs NDT Certificate
These terms are sometimes used interchangeably in the workplace, but they can mean different things.
An NDT inspection report normally records the technical details and results of a particular examination.
An NDT certificate may refer to a certification document, personnel qualification, material certificate, equipment certificate, or another formal document depending on the organization.
For example:
NDT personnel certificate → proves personnel qualification
Material certificate → provides material information
Equipment calibration certificate → provides calibration information
NDT inspection report → records an examination performed on a component
Always use the terminology required by the project's documentation system.
4. Basic NDT Inspection Report Format
A practical NDT report normally contains several sections.
A typical structure is:
Section 1 — Project Information
Client
Project
Location
Purchase order/work order
Component
Drawing number
Section 2 — Examination Information
NDT method
Procedure number
Examination date
Examination extent
Surface or area examined
Section 3 — Component Information
Material
Thickness
Weld number
Joint type
Component identification
Section 4 — Equipment
Manufacturer
Model
Serial number
Probe/transducer/source where applicable
Calibration/verification information
Section 5 — Results
Indications
Location
Size
Type/characterization where applicable
Evaluation
Section 6 — Acceptance
Applicable code/specification
Acceptance criteria
Final result
Section 7 — Personnel
Technician
Qualification/certification information as required
Reviewer/Level III where applicable
Section 8 — Approval
Signature
Date
Review/approval information
The actual format should always follow the project's approved documentation requirements.

Important Note
This sample is provided for learning and reference purposes. It is not an official ASME, ASNT, client, or company inspection form. Actual NDT reports may require additional information such as equipment serial numbers, calibration records, scan details, indication locations, attachments, photographs, radiographs, digital data files, or other project-specific information.
Always use the current applicable code, standard, approved procedure, project specification, and client requirements when preparing an actual NDT inspection report.
5. Project Information
The first section of the report should identify the work clearly.
Typical information includes:
Client:
Name of customer or organization.
Project:
Project identification.
Location:
Where the inspection was performed.
Work Order / PO:
Applicable purchase order or work order number.
Component:
Vessel, pipe, nozzle, structure, plate, weld, casting, etc.
Drawing Number:
Applicable drawing reference.
Report Number:
Unique report identification.
Report Revision:
Revision number where applicable.
This information prevents the report from becoming an isolated document with no connection to the actual project.
6. Why Report Number Is Important
Every report should have a unique identification system where required.
For example:
NDT-RT-2026-0045
could represent:
NDT → nondestructive testing
RT → radiographic testing
2026 → year
0045 → sequential report number
The actual numbering system should be defined by the company.
A report number helps with:
Document control
Retrieval
Revision tracking
Client records
Audit preparation
Traceability
Never invent a numbering system for a project if the company already has an approved system.
7. Component Identification
The report must identify exactly what was inspected.
Depending on the component, this may include:
Equipment number
Weld number
Joint number
Spool number
Line number
Drawing number
Part number
Serial number
Heat number
For weld inspection, the weld identification number is particularly important.
For example:
Weld No.: W-102
The report should allow the reviewer to locate W-102 on the relevant drawing, weld map, or inspection record.
8. Weld Traceability
Weld traceability connects the physical weld to its documentation.
A welding project may have:
Drawing → Weld Map → Weld Number → Welder → WPS → NDT Report → NDT Result
This creates a chain of evidence.
A report should not simply say:
"Pipe weld inspected — acceptable."
That statement provides very little traceability.
A better record identifies the specific weld and examination details.
For example:
Component: Process Piping
Line No.: P-1001
Joint No.: W-045
Welder ID: 127
WPS: WPS-09
NDT Method: RT
Examination Extent: As specified by project procedure
This allows the inspection result to be connected to the fabrication record.
9. Material Information
Material information should be recorded where required by the procedure or project.
Possible information includes:
Material grade
Material specification
Heat number
Thickness
Diameter
Product form
Material identification
For example:
Material: Carbon steel
Thickness: 20 mm
Heat No.: H45821
The exact information required depends on the examination and project.
10. Examination Method
Clearly identify the NDT method.
Examples:
VT — Visual Testing
PT — Liquid Penetrant Testing
MT — Magnetic Particle Testing
RT — Radiographic Testing
UT — Ultrasonic Testing
PAUT — Phased Array Ultrasonic Testing
TOFD — Time of Flight Diffraction
ECT — Eddy Current Testing
Do not simply write:
"NDT completed."
That is too vague.
A report should clearly state which examination method was used.
11. NDT Procedure Reference
The report should reference the applicable examination procedure where required.
For example:
Procedure: NDT-UT-PR-005 Rev. 2
The procedure may define:
Equipment
Technique
Calibration
Examination parameters
Scanning requirements
Evaluation method
Reporting requirements
The report records what was actually performed, while the procedure defines how the examination is to be performed.
12. Applicable Code and Specification
This is one of the most important sections of an NDT report.
The report may need to identify:
Construction code
NDT standard
Project specification
Examination procedure
Acceptance standard
Drawing requirement
For example, an ASME project may use ASME Section V for examination requirements while the applicable construction code or specification provides the acceptance requirements.
Your existing ASME Section V vs Section VIII article explains this distinction in more detail.
Do not write a random code reference simply because it is commonly used.
The report should identify the requirement actually applicable to the job.
13. Equipment Details
Equipment identification provides traceability between the examination and the equipment used.
Depending on the method, the report may include:
UT
Instrument manufacturer
Instrument model
Serial number
Probe/transducer
Frequency
Angle
Calibration/reference block
RT
Radiation source
Source identification
Exposure information
Film/detector information
IQI
Processing information where applicable
MT
Yoke or magnetizing equipment
Equipment identification
Current/magnetization details where required
Test medium
PT
Penetrant system
Cleaner
Developer
Batch/lot information where required
VT
Lighting measurement equipment where required
Visual aids
Measuring gauges
ASNT specifically emphasizes recording manufacturer, model, serial number, and applicable calibration information in a traceable manner.
14. Calibration and Verification Information
Equipment calibration or verification is a critical part of inspection documentation.
Depending on the method, the report may contain:
Equipment ID
Calibration date
Calibration due date
Verification result
Reference standard
Calibration block
Verification before examination
Verification after examination where required
Do not confuse calibration with every routine performance check.
A project procedure may require specific equipment checks before and/or after examination.
The report should record what the approved procedure requires.
15. Personnel Information
The report may identify:
Technician name
Technician ID
NDT method
Certification level
Certification number
Employer
Examination date
Depending on the certification system and project requirements, a report may also require reviewer or Level III information.
Personnel qualification requirements vary by certification scheme and governing requirements.
For example, ASNT's current certification documentation requirements include inspection reports and other employment records as possible evidence of experience for certification applications.
16. Examination Date and Time
The date of examination should be recorded.
Depending on the project, additional information may include:
Start time
End time
Shift
Environmental conditions
Temperature
Surface condition
Not every report needs all of these fields.
The principle is simple:
Record the information required to demonstrate that the examination was performed under the required conditions.
17. Examination Extent
The report should clearly identify how much of the component was examined.
Examples:
100% of weld length
25% examination
One spot
Two locations
Entire accessible surface
Defined scan area
Never assume that "inspected" automatically means 100%.
The examination extent should match the applicable inspection plan, specification, code, or procedure.
18. Recording NDT Results
The result section is the heart of the report.
Depending on the method, record:
No relevant indications detected
Relevant indications detected
Indication location
Indication length
Indication height/depth where applicable
Indication type or characterization
Reference point
Orientation
Evaluation
The report should be factual.
Avoid vague statements such as:
"Looks okay."
Instead write:
"No relevant indications detected within the examined area."
The exact wording should follow the company's approved reporting procedure.
19. Recording Indication Location
When an indication is found, its location should be recorded clearly.
Possible references include:
Weld centerline
Clock position
Distance from weld reference point
Drawing coordinate
Grid reference
Scan position
Component orientation
For example:
Indication location: 180 mm from weld start, approximately 3 o'clock position.
The actual method depends on the examination technique.
The objective is that another qualified person can locate the indication.
20. Recording Indication Size
Depending on the NDT method, report:
Length
Width
Height
Depth
Amplitude
Position
Through-wall location
Do not record parameters that the technique does not reliably measure.
For example, an RT report may record image-based indication dimensions, while UT/PAUT may record location and estimated dimensions according to the applicable procedure.
21. Acceptance Criteria
The report should identify the acceptance standard used for evaluation.
This may be:
Construction code
Product standard
Project specification
Client specification
Approved procedure
Drawing requirement
The report should not simply state:
"As per ASME."
ASME contains multiple sections, articles, paragraphs, and requirements.
A more useful report identifies the applicable document and requirement precisely enough for review.
22. Acceptable vs Rejectable
The final result might be recorded as:
ACCEPTABLE
or:
REJECTABLE
or, depending on the company's system:
PASS / FAIL
But the result should be supported by the examination data and applicable acceptance criteria.
A good report does not hide the technical basis for the conclusion.
23. Important Difference: Indication vs Defect
This is one of the most important concepts in NDT reporting.
An indication is a response or evidence produced by an NDT method.
A discontinuity is an interruption in the normal structure.
A defect is generally a discontinuity that exceeds the applicable acceptance requirements.
Therefore:
Indication ≠ Automatically Defect
The technician or evaluator must determine whether the indication is relevant and whether it meets the applicable acceptance criteria.
Your existing MT acceptance article discusses this distinction in detail.
24. Sample NDT Report — Visual Testing

29. What Should a PAUT Report Contain?
PAUT reports can require more information than a basic conventional UT report because the examination may generate digital data and imaging.
Depending on the procedure, documentation may include:
Component identification
Weld number
Scanner identification
PAUT instrument
Probe
Wedge
Element configuration
Frequency
Scan plan
Calibration
Reference block
Examination coverage
Data file identification
Indication location
Indication dimensions
Evaluation
Acceptance criteria
Final result
The actual requirements should come from the approved procedure and applicable standard.
30. What Should a TOFD Report Contain?
A TOFD report may include:
Component identification
Weld identification
Probe pair information
Probe frequency
Probe separation
Calibration
Scan direction
Scan coverage
Data file
Indication location
Depth
Height
Length where applicable
Evaluation
Acceptance criteria
Final result
Digital data identification is especially important when the examination generates electronic records.
31. NDT Report for Welding Inspection
For weld inspection, the report should ideally connect the NDT result with the welding documentation.
A useful traceability chain is:
Drawing → Weld Map → Weld Number → WPS → Welder → NDT Procedure → NDT Report → Result
This is especially valuable during:
Client inspection
Third-party inspection
Internal audits
Final dossier preparation
Repair investigations
Future maintenance
32. NDT Report for Repair Welds
Repair welds require particularly careful documentation.
The report may need to identify:
Original weld number
Repair location
Repair reference
Reason for repair
Original NDT report
Repair procedure
Repair welding information
Welder
Re-examination method
Re-examination result
A repaired weld should not become disconnected from its original inspection history.
33. NDT Report Revision Control
Sometimes an NDT report needs correction.
Examples:
Incorrect weld number
Wrong equipment serial number
Typographical error
Missing indication location
Incorrect drawing reference
Do not simply change a controlled report without following the company's document-control process.
A revised report may require:
Revision number
Revision date
Description of change
Authorized approval
The original record should remain traceable according to the applicable document-control system.
34. Common NDT Reporting Mistakes
Mistake 1 — Missing Weld Number
Writing "Weld inspected" without identifying the weld creates a traceability problem.
Better: Record the exact weld/joint identification.
Mistake 2 — Missing Equipment Identification
A report saying only "UT machine used" is not sufficiently specific when equipment traceability is required.
Better: Record the applicable manufacturer, model, serial number, and other required equipment information.
Mistake 3 — Missing Calibration Information
If the procedure requires calibration/verification information, it should be documented.
ASNT specifically highlights traceable equipment and calibration information as important parts of report writing.
Mistake 4 — Writing "As Per Code"
This is too vague.
Better: Identify the applicable code/standard/procedure and relevant requirement as required by the reporting system.
Mistake 5 — No Examination Extent
A reviewer may not know whether the weld was examined 10%, 25%, or 100%.
Better: Clearly state the examination extent.
Mistake 6 — Poor Indication Location
"Defect found in weld" is not enough.
Better: Record a clear location reference.
Mistake 7 — Mixing Observation and Conclusion
For example:
"Porosity — reject."
A professional report should distinguish what was observed from how it was evaluated.
Mistake 8 — Wrong Code Reference
Using an incorrect acceptance standard can lead to an incorrect evaluation.
Better: Verify the project requirements before completing the report.
Mistake 9 — Missing Signatures or Review
If the quality system requires review or approval, incomplete authorization can make the report difficult to close.
Mistake 10 — Changing Results Without Traceability
Controlled inspection records should never be casually edited.
Follow the approved revision/correction process.
35. How to Review an NDT Report Before Submission
Before submitting a report, perform a final check.

36. What Attachments May Accompany an NDT Report?
Depending on the method and project, supporting records may include:
VT
Photographs
Sketches
Measurement records
PT
Photographs of indications
Consumable information where required
MT
Indication photographs
Equipment verification records where applicable
RT
Radiographs/digital images
Image-quality records
Technique information
UT
Scan records
Calibration records
Indication data
PAUT
Scan images
Data files
Scan plans
TOFD
Data files
Scan images
Analysis records
The report should identify attachments clearly.
37. Digital NDT Reports
Modern inspection organizations increasingly use digital reporting systems.
Digital NDT records can provide:
Faster reporting
Automatic numbering
Photo attachments
Electronic signatures
Data storage
Searchability
Reduced transcription errors
Better traceability
However, digital reporting does not automatically make a report technically correct.
A poorly completed digital form is still a poor inspection record.
The technical quality of the information remains the priority.
38. Paper Report vs Digital Report
Paper Reports
Advantages:
Simple
Easy to use in field conditions
No software required
Disadvantages:
Handwriting problems
Lost documents
Manual filing
Difficult searching
Greater transcription risk
Digital Reports
Advantages:
Searchable
Easier storage
Faster distribution
Data attachments
Improved document control
Disadvantages:
Software dependency
Training requirements
Data-entry mistakes
Cybersecurity/storage considerations
Both can work if the inspection documentation is controlled properly.
39. What Makes a Good NDT Report?
A good NDT report should be:
Accurate
The information must represent what was actually performed.
Complete
Required fields should not be left blank.
Traceable
The report must connect to the component and inspection location.
Clear
Another qualified person should understand the result.
Objective
Record facts rather than assumptions.
Verifiable
Equipment, procedure, personnel, and acceptance requirements should be traceable where required.
Controlled
Revisions and corrections should follow the applicable document-control system.
40. Practical Example: Reviewing a Weld RT Report
Imagine you receive an RT report for Weld W-101.
The first thing to check is:
1. Is W-101 the correct weld?
Then:
2. Is the correct component identified?
3. Is the examination extent correct?
4. Is the applicable RT procedure identified?
5. Is the equipment/source information recorded as required?
6. Is the image identification traceable?
7. Is the applicable acceptance criterion identified?
8. Are indications recorded?
9. Is the final result clear?
10. Is the report properly signed/reviewed?
If any critical information is missing, clarification may be required before the report is accepted into the quality dossier.
41. Practical Example: Reviewing a UT Report
For a UT report, check:
Weld identification
Material
Thickness
Instrument
Probe
Calibration/reference standard
Procedure
Scan coverage
Indication location
Indication amplitude/evaluation data as required
Acceptance criteria
Result
Inspector identification
This is particularly important because UT results can depend strongly on the examination technique and calibration.
42. NDT Report and Quality Audits
NDT reports are frequently important during quality audits.
An auditor may ask:
"Show me the inspection record for this weld."
The organization should be able to retrieve the report and connect it to:
Drawing
Weld map
Material
Welder
WPS
NDT procedure
Equipment
Calibration
Acceptance criteria
Final result
This is why documentation is not merely administrative work.
It is part of the quality system.
43. NDT Report and Client Inspection
Clients may review NDT reports before accepting fabricated equipment.
A client or third-party inspector may check:
Report completeness
Personnel qualification
Equipment information
Examination extent
Code references
Indications
Acceptance criteria
Attachments
Signatures
A technically good inspection can still create delays if its documentation is incomplete.
44. NDT Report and Final Manufacturing Dossier
For large industrial projects, NDT reports may become part of the final manufacturing or quality dossier.
The dossier may contain:
Material certificates
Welding documents
WPS/PQR/WPQ
NDT reports
Heat-treatment records
Dimensional reports
Pressure-test records
Inspection release documents
Therefore, an NDT report should be prepared with the understanding that it may be reviewed years later.
45. NDT Report Writing Tips for Level II Technicians
If you are an NDT Level II technician, develop these habits:
Tip 1
Write the report immediately after the examination while details are fresh.
Tip 2
Always verify the weld/component number before starting.
Tip 3
Record equipment information from the actual equipment, not memory.
Tip 4
Do not guess calibration information.
Tip 5
Use the approved procedure.
Tip 6
Record actual observations.
Tip 7
Do not change an indication into a "defect" without proper evaluation.
Tip 8
Check the acceptance criteria before declaring the final result.
Tip 9
Review the complete report before submitting it.
Tip 10
Remember that someone else may need to understand your report years later.
46. NDT Report Writing Tips for Level III Personnel
Level III personnel may have additional responsibilities related to procedures, technical review, personnel qualification, and quality systems depending on the applicable certification and employer program.
A strong Level III review should consider:
Procedure compliance
Technical adequacy
Applicable standards
Examination technique
Personnel qualification
Equipment requirements
Calibration
Acceptance criteria
Data interpretation
Reporting requirements
ASNT's current Level III examination information includes responsibilities such as developing documentation of inspection results, evaluating NDT methods, interpreting requirements, and developing/applying procedures.

49. Frequently Asked Questions
What is an NDT inspection report?
An NDT inspection report is a documented record of an NDT examination, including identification of the component, method, procedure, equipment, examination results, evaluation, and final disposition as required.
What information should an NDT report contain?
It commonly contains project information, component identification, NDT method, procedure, examination extent, equipment, calibration/verification information, results, acceptance criteria, personnel, and approval information. The exact requirements depend on the project.
What is an NDT report format?
An NDT report format is the structured form used to record the technical details and results of an NDT examination.
Can one NDT report format be used for all methods?
Not necessarily.
PT, MT, RT, UT, PAUT, TOFD, and VT have different technical parameters, so their reports may require different fields.
Should equipment serial numbers be included?
Where required by the procedure or quality system, yes. Traceable equipment identification is an important part of inspection documentation.
Should calibration information be recorded?
Where required, the applicable calibration or verification information should be documented so that the inspection can be traced to the equipment status.
What is the difference between an indication and a defect?
An indication is an NDT response. A defect is a discontinuity that does not meet the applicable acceptance requirements.
Can an NDT technician change an NDT report?
Only according to the organization's approved document-control and correction process.
Is a report required after every NDT examination?
The requirement depends on the project, applicable procedure, code, specification, and quality system. Where a formal inspection record is required, the report should be completed accordingly.
Why is weld traceability important?
Weld traceability connects the physical weld to its drawing, welding documentation, NDT examination, and final result.
50. Final NDT Report Review Checklist
Before closing the report, ask yourself:

Conclusion
An NDT inspection report is more than a form filled out after testing.
It is the documented evidence of the inspection.
A professional report connects the component, weld, procedure, equipment, personnel, examination results, and acceptance requirements into one traceable record.
The best NDT technician does not simply know how to perform PT, MT, RT, UT, PAUT, TOFD, or VT.
A professional technician also knows how to document the work accurately.
Remember the basic reporting chain:
Component Identification → NDT Method → Procedure → Equipment → Calibration/Verification → Examination → Indications → Evaluation → Acceptance Criteria → Final Result → Traceability
If any important part of that chain is missing, the report may become difficult to verify.
For NDT Level I and Level II technicians, developing strong report-writing habits is therefore an important professional skill.
A good inspection deserves a good record.
And a good NDT report should allow another qualified person to understand what was inspected, how it was inspected, what was found, and why the final result was reached.
