Abstract

Manual laser welding has become one of the progressive technologies in recent years for processing of metallic materials, showing particular advantages in the welding of different metals. By the high energy concentration and precise focus of the laser beam, it is possible to produce joints with minimal heat-affected zones, significantly reducing the risk of deformation, cracking and other types of defects. This technology enables high-quality and aesthetically welds without the need of post-processing, while also increasing productivity and process repeatability.
This article examines the main principles, parameters and modes of laser beam welding itself, analyzes practical parameters of device LW-2000W, designed for manual laser welding. The final section summarizes practical part focusing on welding of sheet metals at different values of parameters such as power, welding speed, wire feed and beam oscillation.
