Dear Friends
AWS D1.1 -It is mandatory all welding shall only be done as min. by qualified and certificated tack-welder BUT
My contrcator argues, if the tack-weld is not going to be part of final weld as the otherside will be backgouged to acheive FP,why the fitter turned tack-welder has to be qualified and certified. Isn't experience is good enough?
How i can convince him?
Thanks
