Joint Design Influence on Laser-MIG Hybrid Welding of Maraging Steel

, 2023
Abstract Laser-MIG Hybrid welding (LHW) was performed in a single- pass on M250 maraging steel plates of 10 mm thickness with three modified joint designs. A Y-groove joint preparation with included angles (IA) of 16°, 24°, and 30° and root face of 2.5 mm was used. Welding was performed using M250 W2 filler wire.
