Resumo

Weld cladding was investigated using a nickel alloy clad on a high strength low alloy carbon steel substrate. The effects of pre-heat temperature, clad material and post-weld heat-treatment are examined, along with the potential for thinner clad layers using laser cladding. Experimental residual stress measurements show good correlation with the simulation model. Metallurgical studies illustrate good fusion between clad and substrate materials. The potential for a fatigue-resistant cladding was demonstrated in a stainless steel clad with the possible use of post-cladding operations to enhance the outcomes for the nickel alloy clad.
