Welding of High Alloy Materials - NeoNickel

Generally any welding process other than oxy-acetylene welding can be used with high alloy materials. The welding process should be chosen to give the best deposition rate that will also achieve the properties required. Consideration should be given to metallurgical or structural properties and SAE AISI 4340 Steel Properties, Heat Treatment, Equivalent Since 4340 alloy steel is air hardened, the welded parts should be either annealed or normalized and tempered shortly after welding. The high hardness of 4340 alloy steel requires that the material be welded in the annealed or tempered state and then heat treated to resist martensite formation and cold cracking. However, as in motor shaft applications, under quenching and tempering conditions, 4340
