Welding of Nickel Alloys. Nickel alloys can be joined reliably by all types of welding processes or methods, with the exception of forge welding and oxyacetylene welding. The wrought nickel alloys can be welded under conditions similar to those used to weld austenitic stainless steels. Cast nickel alloys, particularly those with a high silicon
14/1/2021· Such processes include shielded metal arc welding (SMAC), submerged arc welding (SAW), plasma arc welding (PAW), flux-cored arc welding (FCAW), and the most often used techniques: GMAW and GTAW. Although the ease of welding depends on the specific grade of stainless steel employed, safety concerns must be addressed regardless of the process implemented.
The problems of welding the fully ferritic steels that fall into the pink area, where grain growth and erittlement is a problem, have already been dealt with in Job Knowledge 01. The austenitic stainless steels falling into the yellow area will also erittle but this is as a result of the formation of hard brittle phases called ''sigma'' (σ) and ''chi'' (χ).
