Thanks for your guidance.
Still I am not clear with the concept
ASME Sec IX says all welding shall be done by a qualified welder, So
for tacking groove joint,
welder need to be qualified for groove joint.....?
Or if he qualified for fillet joint, he can allowed for tacking groove
joint (Tack either incorporated into the final weld or removed).....?
please reply
