The high susceptibility to cold crack and reheat crack is a shortcoming with the welding of 1Cr11MoNiW1VNbN martensitic stainless steel. The stellite alloys is a kind of wear-resistant and hard alloys

characteristic with high strength and hardness

poor ductility and poor weldability. Therefore

it is important to choose reasonable welding materials and set the welding and heat treatment process parameters strictly to avoid welding cracks and meet the requirements of surfacing welding. In this paper

through choosing Ni-based Alloy as transition layer and strictly controlling process parameters

the steady and well-surfacing joint was successfully obtained

the feasibility of the surfacing process was proved

the purpose of guiding industrial production was realized also.
