Or can we weld first with ENiCrMo-3(Alloy 625) electrode for root and hot pass(considering cladding thickness is 3mm) followed by CS electrode for CS backing material.
Thanks for response, what could be reason then some of the client ask for buttering with Alloy 625 or 825 on weld bevels on both sides prior to girth welding using E-NiCrMo-3(Alloy825) electrode.
I have Carbon Steel pipe cladded with Alloy 825 and I would like to join two cladded pipes and there is no access from other side(Single sided weld joint). Can I directly weld with ENiCrMo-3(Alloy 825) electrode, without doing buttering on weld bevels prior to girth welding using 825 electrode.
