In the present study, fiber laser has been used in laser cladding with an off-axis powder injection. The aim of this study is to analyze the effects of the laser cladding process parameters on the clad layer geometry. The parameters studied were laser power, cladding speed, and powder feeding rate. This study was conducted by using single-pass clad layers. The powder material used was stainless steel AISI 316L and the substrate material used was structural steel S355. The relationship between the laser cladding process parameters and the clad layer geometry was established by using statistical analysis.
Analysis of the cladding results concluded that the laser power and cladding speed are the main parameters that control the clad layer width. The majority of the variations were in the clad height, but the clad bead side angle was also dependent on the powder feed rate and cladding speed. This study successfully established the relationship between the laser cladding process parameters and the clad geometry.
