Abstract
Re-engineering is gaining attention due to severe environmental pollution and economic crisis. Although re-engineering in shipbuilding has been carried out steadily, technological advancements, domestic ship repair and maintenance industries are not as prevalent as shipbuilding industries. In order to solve this problems, laser cladding can significantly aid with technical development. Laser cladding produces an outstanding clad layer with minimal dilution and little porosity. In this study, prior to applying laser cladding to an exhaust valve face, the effects of various parameters that affect the characteristics of the 1 pass clad layer were investigated. When laser power was increased, the clad layer width became broader and the height was decreased. In addition, it was identified that the hardness of the clad layer was inversely proportional to the power, and the entire clad layer was diluted through an EDS chemical composition analysis.
