Ni Based Manual Metal Arc Welding Electrode
(OP)
can any body tell me why Nickel based MMAW electrodes (Contains arround 90% Ni.) are usually choose upon gray cast iron as a buttering material before going to actual hardface deposition ?





RE: Ni Based Manual Metal Arc Welding Electrode
However high phosphorous and sulphur levels in some grey irons, can contaminate the weld metal leading to solidification cracking.
Hope this answers your question
