Re: [MW:28413] Tack welder qualification

As per UW 31, it refers section IX for qualification of welders and welding operators. There is no separate category as Tack welders as mentioned in AWS D1.1, 4.15.1.2.

All tack welds and welding shall be made by a Qualified welders( There is no separate category for tack welders in ASME, Piping etc). Hope it is clear

Dear Sir
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
