Investigation of the effects of laser welding seam forms on welding properties in sheet metal joints

In this study, the general usage areas of laser welding, its place in automotive, its important parameters and the effects of laser seam geometries on different joining types and different loading conditions were investigated. The effects of laser power and welding speed parameters on weld penetration have been studied in a macro scale. Welds in different seam geometries were applied with the determined optimum welding parameters and they were subjected to tests under different loading conditions. It is predicted that these studies will help the appropriate seam form selection stage in the use of laser welding method instead of the joining methods currently used in the industry. In this way, the process steps will be shortened and the welding will be performed in an optimum way.
