Abstract
Laser Beam Welding (LBW) of complex materials, such as ferritic and austenitic steel, is challenging. An appropriate beam shape improves the process by stabilizing the keyhole. A methodology for tailoring the beam shape has been developed. The appropriate shape for LBW of 1mm thick steel is an inner intense spot and a background top-hat shape. A dynamic beam shaper based on Multi-Plane Light Conversion has been developed: the ratio between the shapes and the back shape dimensions can be adjusted. The optical performance and the impact on the quality of the process with a 8kW 1.07µm laser are described.
