I have following case"

GTAW+FCAW PQR , GTAW was done manually in 5G position while FCAW was done in 1G position on machine.

Case-1 Without Impact Test Requirement

Position qualified as per QW 405.1 - non essential variable "The addition of other welding positions than those already qualified".

Question: Can we prepare WPS mentioning FCAW qualified welding position for all or 5G position as "addition of other position is non essential variable" and also as per QW 203 " a qualification in any position qualifies the procedure for all positions?

Case-2 With Impact Test Requirement

Position qualified as per QW 405.2 - supplementary essential variable

Question: Can we prepare WPS mentioning FCAW qualified welding position for all or 5G welding with downhill progression as QW-405.2 only considers "change of any position to the vertical position uphill progression."

Need valuable feedback on this.

ASME IX only invokes impact testing where required by the constructing code. The constructing code can add, delete or modify requirements of ASME IX. Since you don't mention the constructing code there isn't enough information to provide a good answer.

Hi Jon,
I have asked 2 scenarios in which impact requirements are required/not required by the construction code.If we consider ASME B31.3 then what would be the answer?

Case 1: YES

Case 2: YES, HOWEVER not sure how much success you'd have in running FCAW vertical down... seems like it would be prone to slag contamination issues and related defects / discontinuities.
