Dear all,

The question is " Can we do tack weld by pipe fitters according to ASME 31.3? "

so, we should go to ASME B31.3.

The Code said on part 328.5.1 (c) Tack welds shall be made by a qualified welder or welding operator.

Hi,

Qualification is required (see applicable design code).

e.g. ASME VIII/1, UW-31 CUTTING, FITTING, AND ALIGNMENT
….
(c) …..Tack welds, whether removed or left in place, shall be made using a fillet weld or butt
weld procedure qualified in accordance with Section IX. …
