I want to know the exact cause off transverse crack observed visually on the surface of the weld.
Welding done with SAW
Material - SA 516 GR. 70
Thickness- 32 mm
We have done pre heating at temperature 100 deg. C but from top side also check the filler wire material
after crack are observed which are ok.
Please share your experience with me on this issue.
Regards,
Nilesh
