Which ASME section covers welder qualification?

Which ASME section covers welder qualification?

• A. ASME Section IX
• B. API 580
• C. ASME Section V
• D. ASME Section VIII

Answer: (A)

Welder qualification is governed by ASME Section IX, Welding and Brazing Qualifications. This section specifies how welders and welding operators must be qualified and how welding procedures themselves must be qualified, including the tests, acceptance criteria, and records (such as the qualification test results) used to prove a welder can produce sound welds. It also defines how a Welding Procedure Specification (WPS) is tied to a Qualified Welding Procedure Record (PWPR/PQR) so that fabrication in other sections, like Section VIII, can rely on proven welding performance. Other ASME sections cover different aspects—Section V deals with nondestructive examination, and Section VIII focuses on design and construction—while API 580 is a separate standard outside ASME.
