For fabrication of any equipment we require welders and welding operators must be qualified as per the qualification standard referred by the construction code. Whenever construction is as per ASME construction codes (like ASME B31.1, B31.3 or ASME section VIII) ASME section IX is used for the qualification of the procedure and welder. Welder is […]
This article is about diameter restrictions and welding position qualification involves in welder and welding operator qualification as per ASME Section IX. Diameter Restriction for Welder Qualification (as per QW-303) 1) If welder is qualified by groove weld during test, then the qualification range will be below (as per table QW-452.3 and table QW-452.6) Note:
In this article we will discuss the thickness qualification range of base metal and weld metal for Procedure qualification and Welder performance qualification as per ASME code. Thickness Qualification Limit for Procedure Qualification (PQR) 1) As per ASME Section IX a) For Groove Weld (As per table QW-451.1) Note- For PQR there is no any
