[MW:33323] RE: 33319] CS material, E70S2- Welder qualified , can he weld SS 316 material & Duplex, Super duplex material with E70s2 qualification ? or he should be qualified by separate SS 316 & Duplex ,SDSS material ?

Hi,

The welder is not qualified to weld SS 316 or DSS or SDSS. Though the F No for consumables remain to be the same , the P No gets changed. Hence welder will require new qualification.

 

Thanks.
