Abstract
In this study the microstructural and compositional variations that exist across a laser-clad weldment produced with a heat input of 150 J/cm and filler wire composition Cu-9.0% Al, 4.6% Ni, 3.9% Mn were characterized. The weld metal, heat-affected zone and casting base metal structures and elemental distributions were evaluated using light optical microscope and electron microphobe, respectively. The results show that a considerable range of microstructures and some significant compositional variations are present in the laser-clad weldment investigated.
