Abstract

Laser welding has become a highly effective technique for joining of metal sheets, offering precision and minimal thermal distortion. The quality of the welds, however, is significantly influenced by the proper selection and control of process parameters. This study focuses on the optimization of key parameters like laser power, welding speed, wire feed rate, and beam oscillation through experimental welding trials.
The practical part of the research involved welding thin sheets with LW-2000W device at various parameter settings, followed by visual inspection and metallographic analysis of the final welds. The findings provide insights into how parameter optimization can enhance consistency and overall process reliability, offering valuable guidelines for industrial applications where high precision is required.
