Abstract

Laser Beam Welding (LBW) finds widespread use in industries like naval and automotive. To meet the demands of complex welding processes, higher power lasers have been developed. However, conventional refractive optics limit power utilization, affecting robustness. Multi-Plane Light Conversion (MPLC), a fully reflective technology, enables complex beam shaping with 16kW lasers. A MPLC-based laser head with an 800µm annular shape at 1µm wavelength has been developed. LBW of 304L stainless steel (6mm thick) at 7kW and HLAW of steel (16kW) with 23mm penetration depth are successfully demonstrated. MPLC's extended depth of field improves welding efficacy, showcasing its potential in advancing laser welding applications.
