Dear All,

I can not see anywhere in AWS D1.1, 2006 mentioned about Alternate Base Materials for Welder Qualification like ASME IX-2006, QW-423. Please inform me about this problem.

Thanks & Best Regards

There is no problem. Base metal specification is not an essential variable for welder qualification in D1.1. Welder qualification must be performed in accordance with a WPS (which could be either prequalified or qualified), but a change in Group Number or to an unlisted base metal is not an essential variable for performance qualification.
