Effect of laser power, welding speed and linear energy density factors to mechanical properties in fiber-laser welding of AISI 316 stainless steel
Austenitic stainless steels are widely used in various industries, including petrochemicals, food processing, and textiles, due to their excellent corrosion resistance, acceptable mechanical properties, and cost-effectiveness. Additionally, their good weldability makes laser welding a popular choice for manufacturing various designs. However, achieving optimal weld quality in laser welding requires precise and controlled adjustment of several key parameters. In this study, the effects of two fundamental process parameters—laser power and welding speed—on the mechanical properties of laser-welded AISI 316 stainless steel structures were investigated. For this purpose, a 2-factor, 3-level full factorial experimental design was implemented. The welded structures were subjected to tensile testing, and their microstructures were analysed.
