Which section of the ASME BPVC deals with welder qualification and development of welding procedure acceptance criteria?

• A. Section IX
• B. Section II Part C
• C. Section VIII
• D. Section I

Answer: (A)

Welder qualification and the development of welding procedure acceptance criteria are addressed in the section that governs how welders and welding procedures are proven capable. This section outlines the performance tests welders must pass and the criteria used to accept welding procedures, including how to document and validate a Welding Procedure Specification (WPS) and a Procedure Qualification Record (PQR). In other words, it sets the requirements for proving that a welder can consistently produce sound welds and that a welding procedure can be relied upon to produce those welds under the specified conditions. Other sections cover design rules, vessel construction, or materials and filler metals, but not the qualification and procedure acceptance process.
