Simulation Study on Weld Formation in Full Penetration Laser + MIG Hybrid Welding of Copper Alloy. [PDF]
Materials (Basel), 2020 Considering the coupling of a droplet, keyhole, and molten pool, a three-dimensional transient model for the full penetration laser + metal inert gas (MIG) hybrid welding of thin copper alloy plate was established, which is able to simulate the temperature and velocity fields, keyhole behavior, and generation of the welding defect.

Research on Weld Formation Mechanism of Laser-MIG Arc Hybrid Welding With Butt Gap [PDF]
Optics and Laser Technology, 2021 Abstract At present, there are few researches on laser -MIG arc hybrid welding with a large butt gap. In this paper, laser-MIG arc hybrid welding is used to weld low-alloy high-strength steel with a thickness of 3 mm, and a laser-MIG arc hybrid welding process under large gap conditions is developed.
