RE: [MW:24896] RE: 24837] welding of cladded (alloy 625) pipes with single side access

Dear Pardip

Thanks for your help and sending that practical guide my proposal is;

Buttering of the edge of joint up to 1/3 of pipe thickness by INCONEL 625 filer (ENiCrMo-3 /ERNiCrMo-3), then continue welding of root pass by INCONEL 625, after completion of root pass fill and cap the joint by carbon steel electrode/filer.

what do you think about it?

Regards,

Himan Nikdin

Hi Himan,

 

Please see the practical guideline for your reference. The highlighted texts would be helpful. Feel free to ask if have any clarifications. For single sided FP welds, ER-NiCrMo-3(625 type) consumables are the only options.

 

Thanks.
