Welding of 825 Cladded material
Welding of 825 Cladded material
(OP)
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.

But passing the corrosion tests is very dependent on the heat input in the CS welds.
Too much heat can be bad.
Make sure that your alloy passes extend deeper than the clad by a good amount.
When you can get at both sides they usually weld the CS root and second pass first, then grind the alloy side and finish out the alloy welds, and then finish the CS welds.
