ASME Section IX

ASME Section IX is the welding and brazing qualification code, defining requirements for Welding Procedure Specifications (WPS), Procedure Qualification Records (PQR), and welder/operator performance qualification used by all ASME construction codes.

Definition

Section IX classifies welding variables as essential, supplementary essential, and non-essential, and defines which require requalification when changed. Although Section IX itself is not an NDT code, its PQR records require RT or UT acceptance and welder qualification is verified by RT or bend test.

Where this comes up in practice

Terms like this one appear in three places that matter commercially: the written practice that governs how your personnel are qualified, the procedures and technique sheets that define how an examination is actually performed, and the evidence an auditor or client asks for when they want to know why an inspection was accepted. Getting the terminology right is the easy part; being able to produce the qualification record, the calibration traceability and the procedure revision that applied on the day of the inspection is the part that decides audits.

Atlantis NDT provides NDT training and certification against ASNT SNT-TC-1A and ISO 9712, ASNT Level III consulting for written practices and procedure approval, inspection management software that holds qualification, calibration and procedure-revision evidence in recoverable form, and an asset integrity platform that binds inspection results to the asset they describe.
