Abstract

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.
