[MW:1881] Welding of Magnetised material


Hi,

Preheating the material upto certain temperature(dempends on material)  will reduce residual magnetism in the material.

This will reduce the Arc blow problem & can be welded with conventional methods.

HI !.
One of the way to reduce the effect of magnetic perturbation is to use AC welding machine.

Dear all,

 

My name is Fernando, marine engineer from Brazil and, next week, I will have to develop a welding procedure in carbon steel in a closed ambient with magnetic field of 60 Gauss.

 

Do you have some tip / information about how would be possible minimize the effects of this magnetic perturbation?

 

Thanks

 

Fernando
