Pock marks are not truly a “defect”. These typically are cosmetic surface blemishes which have no effect on the actual quality or functionality of the weld.

| Dear Mr.Sreevalsan,
Thanks for providing the details. I have faced the same problem. In SAW weld I have observed surface dippression. What is the root cause? Can we take any precaution at welding stage? Who is responsible for this type of defect? flux mfr/ wire mfr./ user? How to avoid it.
I am not sure, this problem may be due to excessive heap of flux on molten weld pool.
can you enlighten us.
With Regards,
Rutvik
