Re: [MW:18792] Re: using of second welder while welding SS material

Ofcourse dharma,
Since you are using 2 welders, 2 various heat inputs, you have to mention in your WPS as the way you have done in PQR. WPS is a work instruction to welding foreman and welders so you must include all technical info in to the WPS , simply not depend on code's essential and supplementary variables.

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.
