GMAW-S Short Circuiting Process is most used for Root Pass,Reason being
Molten weld puddle is able to freeze more quickly than welding with a continuous arc & less voltage required.
ASME Section IX applied special variables when the GMAW-S process is used. When qualifying a welding procedure, the variable QW-403.10 limits the base metal thickness qualified to a maximum of 1.1 times the test coupon thickness for procedure qualification test coupons less than l/2 inch thick. The variable QW-404.32 also limits the deposited weld metal thickness range to a maximum of 1.1 times the deposited thickness of the procedure qualification test coupon for deposits less than 1/2 inch thick.
It can be used for P1 group materials
Hello All
As Per ASME Sec VIII div.1, which GMAW we can use for root pass
for "P1" group materials and what is min < t < max ?.
Thanks
