Interpretation: IX-77-04 Subject: Section IX, Tack Welder Qualification Date Issued: January 31, 1977 File: NA Question: May a welder be qualified as a tack welder if his tack welds were a part of another welder's qualification test coupon or part of another welding procedure qualification test which met the intent of the Code? Reply: The Code requires that all welders, (including tack welders), must be qualified per Section IX. Interpretation: IX-78-16 Subject: Section IX, QW-255, Flux Cored Arc Welding Date Issued: February 27, 1978 File: BC77-502 Question: Does gas metal-arc welding (GMAW) in the procedure qualification and performance qualification refer also to flux cored arc welding (FCAW)? If so, should welders be qualified separately under both processes? Reply: Flux cored arc welding (FCAW) is permissible under the Code and is considered to come under the more general method of welding known as gas metal-arc welding (GMAW). Welders do not have to be qualified separately unless there is a change in any of the Essential Variables. However, there is an Essential Variable for procedure qualification, QW-404.23, that requires separate qualification for solid wire and for flux cored wire for the GMAW process.
