Fillet weld preheat
Fillet weld preheat
(OP)
We have an AWS qualified CS(P1 to P1)WPS,without preheat.
We have 40 to 50 mm CS base material that requires 10mm fillet welds on 2 sides. Required preheat for this thickness
is per Table 3.2, 150F / 65C. Can I use the qualified AWS WPS (without preheat)to weld these fillets, preheating as required for the thickness, or must I qualify another WPS
with the required preheat.
