I am working in fabrication company of piping.My company divided the the welders in two different area-(1) tack welders & (2) welders.Tack welders are working at fitup section & welders are working in welding area.Now my question is that-is it required to qualify the tack welders?If yes then why? If yes than how i will proceed & how to make the prolongation of tack welders?

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
