Hot cracking tendency of flux-cored arc welding with flux-cored wires of types Ni 6625 [PDF]
Welding in the World, 2021 AbstractDue to their mechanical and corrosive properties, nickel-based alloys are very important in several industrial sectors like power stations, chemical apparatus, and the oil industry. While flux-cored arc welding (FCAW) of carbon steels often uses flux-cored wires (FCW), the use of Ni-based flux-cored wires is industrially less common.
