Re: [MW:18826] RE: 18787] Re: using of second welder while welding SS material

Mr. Dharmadattu.B

 

Have you already qualified the procedure with such arrangment ? The way it is described, it would be really difficult to control the weld properties manually-  simultaneously with two welders welding from opposite sides at a time. It would be nice, if your experience would be shared.

Dear Experts,

While welding of SS material we need to supply a backing gas, as an alternative a second welder is deployed from back side to support or to melt the weld metal uniformly. is this method to be included in WPS's or is this a general practice.
