Nickel Alloy Electrodes
Alloy A (ENiCrFe-2) electrodes are used for welding of nickel-chromium-iron alloys to themselves as well as for dissimilar welding between various nickel alloys and carbon or stainless steels. There is a large range of applications from cryogenic temperatures up to 1500°F. These electrodes can also be used for overlay cladding where similar alloy is needed.
