For the fillet welds between the skirt and the lower head, does the welding procedure qualification required need to cover both the thickness of the skirt and that of the head? The thickness of the skirt is 16 mm, while that of the lower head is 50 mm; the material used is Q345R, with TIG welding used for the root pass and manual welding for the finish pass. Does the TIG welding assessment required must cover 50 mm?
The weld thickness is independent of the base material thickness.
The weld thickness is independent of the base material thickness. Then what is the purpose of the standard-defined range for the thickness of the test piece base metal?
In fact, this is a buttweld, and of course a weld assessment is required to cover the thickness of both base metals
Do you think it’s necessary for his weld evaluation to cover 50mm?
