Ultrasonic Testing (UT) Weld Inspection Report Template

A manual pulse-echo UT report for butt and fillet welds, laid out so every field a code reviewer checks is on the page: equipment and probe identity, calibration, scanning sensitivity, and a location-referenced record of every indication.

What a compliant UT weld report must contain

ASME Section V Article 4 splits the paperwork into two layers. The examination record (T-492 in recent editions) carries the general Article 1 record items plus the UT specifics: the instrument identified by manufacturer serial number, each search unit identified by serial number, frequency and size, the beam angles used, the couplant by brand or type, and the search unit cables by type and length. The report itself (T-493) must add a record of the welds or volume examined, which can be a marked-up sketch, the location of each recorded reflector, and the identity of the operator who carried out each examination or part of it.

Older editions word this as a single list that also names the procedure, the calibration sheet identity, the surface the examination was conducted from, the surface condition, the frequency, the calibration block and any special equipment. Clients and Authorized Inspectors still expect all of those, so the template keeps them even where a newer edition folds them into the procedure reference. Check which edition your contract or the referencing construction code calls up; paragraph numbers move between editions, the substance does not.

Under ISO 17640 the test report is equally prescriptive: it identifies the object, material, weld preparation and thickness, the testing level, the equipment and probes, the reference method and sensitivity (DAC, DGS or reference-block), the scanning surfaces and extent, and the indications with position, length and echo height. Acceptance is then judged against ISO 11666 acceptance levels or the product standard, not against ISO 17640 itself.

• Traceability: weld number tied to the drawing revision, the WPS and the welder stamp where the client asks for it.
• Calibration evidence: reference block ID, reference level (for example the DAC primary reference), scanning sensitivity above reference, and the transfer correction applied.
• Indication record: position along the weld from a stated datum, depth, length, maximum amplitude relative to reference, the probe that found it, and its evaluation.
• People: the examiner and the reviewer with method, level and certification scheme, plus the client or third-party acceptance if it was witnessed.

How to fill it in without getting it bounced

Most UT reports that come back from a client reviewer come back for the same handful of reasons. The datum is missing, so nobody can find indication 2 again. The probe serial numbers are on the calibration sheet but not on the report, so the report cannot be tied to the calibration. The reference level is stated but the scanning level is not. Or the report says "no recordable indications" without saying what the recording level was.

1. State the datum on every weld (for example "0 at top dead centre, clockwise looking with flow") and use it in the position column.
2. Record the recording level as well as the reference level, so "no recordable indications" has a meaning.
3. Give each indication its own row, even when two indications sit on the same weld; merged rows are the first thing a reviewer questions.
4. Record the evaluation and the result separately: the evaluation is what you believe the reflector is, the result is the decision against the acceptance standard.
5. Keep the calibration check times (start, intervals and end). A failed end-of-shift check means re-examining everything since the last good check, and the report must show which welds that covered.

If the job is UT in lieu of radiography under a construction code, the report must also show the specific extra requirements that code places on the examination, such as the use of a computerised imaging technique or a performance-demonstrated procedure. Those belong in the procedure reference and in the remarks block, never left for the reader to assume.

Recording scanning coverage on the report

A UT result is only as strong as the coverage behind it. The report should let a reviewer see which beam angles were used from which surfaces and sides, whether the full weld volume plus the required width of heat-affected zone was covered, and where access limited the scan. A sketch showing scan surfaces and any restricted zones is worth more than a sentence claiming "100% coverage". Where a restriction exists, say what was done about it: an additional angle, a scan from the other side, or a note that the area needs a different method.

The header fields every NDT report shares

Whatever the method, a report is only useful if it can be tied to the job, the drawing and the people. Every template in this library starts with the same header block: report number and revision, date, client, job and work-order references, site, component, drawing and revision, procedure and revision, acceptance standard and extent. ASME Section V Article 1 sets general record requirements that each method article then builds on, and client specifications almost always add their own. Keeping the header identical across methods means a reviewer, or the software that reads your reports later, always finds the same facts in the same place.

Generate these reports automatically in Atlantis NDT Reporting

A template solves the layout. It does not stop the same job, drawing, procedure, instrument and technician details being typed again on every report, or a report going out before anyone checked the technician's certificate was in date. In Atlantis ERP, the NDT Reports app holds UT as its own report type with its own numbering sequence, captured in an offline field app with photos and on-screen signatures, then moved through draft, review, approval and sending with inspector, reviewer and approver signatures.

In the NDT Reports app, a UT report carries a probe calibration table, so each probe row holds its serial number, frequency, angle and reference level, and the weld lines hold the defect type, orientation and result. The job, work order, drawing and WPS references come from the job, so they are typed once. The overall result is recorded as acceptable, not acceptable or acceptable with remarks.

Your company format is kept: templates can be versioned in Excel, Word, PDF or HTML with your logo, header and footer, and Excel templates are filled automatically by mapping fields to cells. When the report is approved, Digital Twin Reporting can place its results on a 3D model of the asset, so clients find reports by location rather than by file name.

See UT reports generated in Atlantis, or keep using the template: both are fine starting points.

Frequently asked questions

Which ASME Section V paragraphs cover UT report contents?

In recent editions, Article 4 T-492 lists the examination record items (instrument and search unit serial numbers, frequency and size, beam angles, couplant, cables) on top of the general Article 1 record items, and T-493 requires the report to identify the welds or volume examined, the location of each recorded reflector and the operator. Paragraph numbering changes between editions, so cite the edition your contract names.

Is ISO 17640 an acceptance standard?

No. ISO 17640 sets out techniques and testing levels for manual UT of welds. Acceptance levels come from ISO 11666 or from the product or application standard named in the contract.

Should the report record indications below the acceptance limit?

Record everything above the recording level your procedure sets, then evaluate. A record of non-rejectable indications lets the next inspection compare like with like, and several referencing codes require it.

Can one report cover several welds?

Yes, as long as each weld has its own line, its own datum and its own result. A report that lists welds but only gives one overall result will usually be rejected.

Who signs a UT weld report?

The examiner (certified in UT at the level your written practice allows to evaluate and report), a reviewer where your procedure requires one, and the client or third-party inspector if acceptance was witnessed or reviewed.
