In the spirit of instigating conversation;
AWSD1.1 does not require a CWI to witness and stamp WQTR's? Only a person trained in the art, doesnt have to be a CWI?
Welders do not have to qualify to a production WPS, only one of the welder qualification test of Clause/Section 4. Those test are what qualifies them to Pre-Qualified WPS's?
