Re: [MW:18758] using of second welder while welding SS material

Any use of backing  / purging gas in TIG welding process should be mentioned in WPS. including type of gas, its flow rate,
composition level etc.
A second welder can perform  only after grinding the root  to sound weld metal  and not in parallel. This also to be mentioned
in WPS if carried out.

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. 

Regards,
