RE: [MW:24326] acceptance criteria for undercut

Hi Martin,

 

A little bit of grinding to remove undercuts and subsequent  GTAW wash pass (w/wout filler metal) would solve the problem. Depending on the corrosivity of process fluids, undercuts may initiate leaks also.

 

Thanks.

Hi experts in welding inspection

 

Is attached highlighted undercut acceptable assuming the depth in pipe edge is max 0.5 mm

 

pipe is welded to slip on flange from front side so it is internal weld from flange face side

construction code is ASME B31.3

Can you refer to code sections?

 

regards

 

Martin.
