Whether Qualification of CS-SS is Valid for CS-CS and SS-SS

10/01/2014 8:07 AM

I qualified a SMAW based WPS using base metals as carbon steel and stainless steel. Can I use this WPS for welding Carbon Steel to Carbon Ssteel of same grade and thickness that qualified? Also is it true for stainless steel also? As per ASME this does not look to be permitted. However, I fail to understand the metallurgical reason. Can anybody clarify?

I believe you have to append your WPS to accommodate this procedure.
