Passes per Layer ??? (with respect to last layer) in Groove Weld.
ASME Section II part C - SFA 5.1/5.1M & SFA 5.5/5.5M says the passes per layer shall be 2 for all the layers of Groove weld.
But while doing actual welding, we are experiencing some problems like weaving to more width and slag inclusions in the last layer.
If we do three passes in the last layer, the problem can be avoided.
Is it acceptable to do three passes in the last layer???
Thanks & Regards,
