RE: [MW:13793] effect of SOOT formation on base material

Hello Asad Azmi,

What was the method used for preheating?

The soot formation as seen on the photos attached should not have any adverse effect on the material, however you will need to clean it before further processing.

Dear All,

 

Greetings.

 

During preheating of a weld joint  SOOT( Black spots) was observed on the base material ( SA 516 GR 70- 50 Thk). Please refer attached photo.

 

Please explain is there any  adverse effect on base material becuase  of the SOOT formation.

 

Thanks & Regards
