[MW:6161] RE: 6154] Transverse Crack

Mostly these crackings are related to hydrogen.

Can you please specify filler metal (wire – flux combination) and hydrogen precautions (redrying?) and thickness.

 

 

With kind regards, mit freundlichem Grüss, salutations, met vriendelijke groet,

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
