Re: [MW:9784] Having GTAW, 6G, 8"Dia 5 to 25.4mm WPS, 2" welder qualification posible or not? as per ASME Sec 9

I think 452.3 can not apply to WPS as 452.3 is for performance qualification and not procedure qualification.

I think WPS is qualified for all diameters as per section ix and for welder qualified with above wps by welding 2'' pipe, his qualification range (diameters )will be governed by 452.3
