The Repair of Defects in High-Manganese Steel Castings by Welding Technology

Abstract:

Welding technologies are used to repair defects in cast parts of high - manganese austenitic steel (Hadfield steel). These include repair welding for newly manufactured castings, welding the formed defects in the old operating cast parts and, finally, for cladding layer of wear-resistant metal on the surface of the cast parts. Manual metal arc welding (MMAW) are used as often as gas metal arc welding (GMAW) and of flux-core wire welding (FCAW-S). These welding processes make possible to obtain a weld metal with the expected quality of the restored surface and a slight distortion of the base metal structure. The article presents methods of the casting repair by welding and surfacing. The parameters of welding and surfacing procedures are given, welding materials are recommended, and the methods for nondestructive testing of welds are prescribed.
