Our company has an ASME GMAW PQR/WPS, P1 base material, ER-70S-6 AWS A5.18, F No. 6. Do the welders that qualify to this GMAW spec. also qualified on FCAW AWS A5.20, E71T-1, F No. 6.
Only if your not going to from short circuit another transfer mode or Vice-versa(see 409.2 -2001). and as long as all the other essentials of QW-355 are followed. but you should have a WPS for FCAW if your using FCAW! ASME only differentiates FCAW and GMAW in PQR's/WPS's (404.23).
