Equipment Calibration Records for AWS D1.1
AWS D1.1 names this requirement as "UT equipment qualification and calibration records against IIW-type or other approved reference blocks (8.23, 8.24, 8.27)". The equipment custodian owns it, and a contracted Level III can author and sign it.
The finding auditors record against this document is: UT equipment qualification and dB accuracy certification records not maintained. D1.1 is a code, not a certification scheme — nobody issues a D1.1 certificate to a company. What it does is dictate who may inspect, how NDT must be procedured, and what constitutes acceptance. Clause 8 is the inspection clause and runs in seven parts: general requirements, contractor obligations, acceptance criteria, NDT procedures, radiographic testing, ultrasonic testing of groove welds, and other examination methods including radiation imaging systems and advanced ultrasonic systems. The 2025 edition rewrote how NDT personnel certification is established, added definitions splitting MT and PT indications into linear and rounded, and updated the Table 8.1 visual acceptance criteria for undercut and piping porosity.

Clause-level detail for 8.10.1, 8.14.6, 8.14.6.2, 8.14.6.3 and 10.29.1 taken verbatim from the AWS Welding Journal article "What's New in AWS D1.1 2025, Structural Welding Code — Steel" published by AWS/FABTECH. Current designation D1.1/D1.1M:2025-AMD1 confirmed on aws.org. AWS QC1:2016, Standard for AWS Certification of Welding Inspectors, read in full (clauses 8.1 visual acuity, 10.1 certification validity, 15 renewals, 16 nine-year recertification). ASNT standard editions confirmed on asnt.org: SNT-TC-1A (2024), ANSI/ASNT CP-189 (2024) and ANSI/ASNT CP-105 (2024) as employer-based, ANSI/ASNT CP-9712 (2023) as the US adoption of ISO 9712:2021 and third-party. Verified August 2026. The full body text of Clause 8 sits behind AWS's paywall and was not read line by line.

What must a equipment calibration records contain under AWS D1.1?
It has to satisfy AWS D1.1 as American Welding Society (AWS), D1 Committee on Structural Welding; an ANSI-approved American National Standard. Welding inspector certification is administered by the AWS Certification Committee under AWS QC1. Enforcement is by the Engineer and Owner through the contract documents, and carries statutory force wherever a governmental body incorporates the code into law or regulation. enforces it: the traceable evidence that every instrument was in calibration on the day it was used. The test is not completeness on paper but traceability — an auditor picks a finished job and works backwards to this document, so anything it claims must be demonstrable on that job.
Who signs the equipment calibration records for AWS D1.1?
The equipment custodian. Because this regime accepts employer-based certification, that role can be filled by a contracted Level III rather than a staff appointment, provided they are qualified in the methods they sign for.
How does a AWS D1.1 auditor test this document?
By sampling. They take a completed job, find the technicians and equipment used, and trace each back through this document to the evidence behind it. A document that reads well but cannot survive that trace is the most common finding across every regime, not just this one.
How long must AWS D1.1 records be kept?
The code is reissued on roughly a five-year cycle: D1.1/D1.1M:2025 is the 25th edition, approved by ANSI on 19 March 2025 and revising D1.1/D1.1M:2020; the currently published designation is D1.1/D1.1M:2025-AMD1. Personnel credentials renew on their own clocks. Under AWS QC1, welding inspector certification is valid for three years; renewals are limited to two consecutive three-year periods, and before the end of the ninth year from initial certification the inspector must recertify — by examination, by a Committee-approved endorsement, or by experience and continuing education. A CAWI is not eligible for renewal and may hold that certification for up to three years only. Visual acuity examinations must be performed no more than one year before the examination date or the expiry date for renewals and recertifications. Retention is set by the regime and by the client contract above it, and the longer of the two governs. Firms that set one retention period for everything and document it fare better at audit than firms tracking different periods per record type and losing track.
Does a generic template satisfy AWS D1.1?
No. A downloaded template describes a generic firm, and the first question an auditor asks is whether the document describes THIS firm — its methods, its equipment, its people, its actual workflow. Templates are a starting structure; the content has to be the firm's own or the trace fails immediately.
What happens if this document is missing at a AWS D1.1 audit?
It is a finding, and depending on the regime it can suspend the certificate rather than merely generate a corrective action. The related finding auditors record most often is: No written practice on file where NDT personnel are certified under the employer-based route of 8.14.6.2
Where this sits in the AWS D1.1 evidence pack
- Employer's written practice for NDT personnel qualification and certification, per ASNT SNT-TC-1A or ANSI/ASNT CP-189 (8.14.6.2)
- NDT personnel certification records, or current ANSI/ASNT CP-9712, CAN/CGSB-48.9712 or ISO 9712 certificates where the third-party route is used (8.14.6.3)
- Written NDT procedures for each method used (Clause 8, Part D)
- UT procedure for tubular T-, Y- and K-connections prepared by an NDT Level III (10.29.1)
- Inspector qualification records for both the Contractor's Inspector and the Verification Inspector (Clause 8, Part A)
- Radiographs together with their examination, report and disposition records (8.18)
- Ultrasonic test reports (8.26) and dB accuracy certification records (8.31)
- UT equipment qualification and calibration records against IIW-type or other approved reference blocks (8.23, 8.24, 8.27)
- Visual inspection records evaluated against the Table 8.1 acceptance criteria
- Engineer's written approval where alternate acceptance criteria are used (8.8)
Personnel certification context
Explicitly dual-track since the 2025 edition. Subclause 8.14.6, Personnel NDT Certification, now carries subclauses: 8.14.6.2, Employer-Based Certification, allows NDT personnel to be certified in accordance with the employer's written practice by ASNT SNT-TC-1A or ANSI/ASNT CP-189; 8.14.6.3, Internationally Recognized Third-Party Certification, allows certification by ANSI/ASNT CP-9712, CAN/CGSB-48.9712 or ISO 9712. Employer-based certification is therefore squarely accepted, and an outsourced Level III can own the written practice and certify the technicians. Clause 10.29.1 goes further for tubular work: UT of T-, Y- and K-connections shall be performed to a written procedure prepared by an NDT Level III, with Level III certification obtainable through SNT-TC-1A and CP-189.
