Dear Experts,

Greetings !!

I have a qualified WPS with a combination of welding processes SMAW & FCAW and the procedure is qualified is without backing but for FCAW the weld metal of SMAW is considered as backing material. As per ASME sec IX for both the processes deletion of backing is not an essential variable. 

My question is Can I use this WPS for making root pass using FCAW process(as deletion of backing is non essential as per Sec IX)? The base metal thickness and deposited weld metal thickness are with in the range.
