目前关于激光+电弧复合热源焊的研究主要集中于工艺方面，即通过试验的方法

At present, the research on laser + arc composite heat source welding mainly focuses on the process, that is, the effect of different process parameters on the welding seam formation of the composite welding is analyzed by the test method, so that the process can be applied to the actual production as soon as possible, and the compound welding machine There are still few scientific studies, and due to the limitations of test conditions and the complexity of the physical mechanism, the research on composite welding fluids is even less, and mainly rely on numerical simulation technology.

At present, the research on laser-arc composite heat source welding mainly focuses on the process, that is, the influence of different process parameters on composite weldforming by test method is analyzed, so as to be able to apply the process to actual production as soon as possible, and the research on the compound welding mechanism is still less, and due to the limitation of test conditions and the complexity of the physical mechanism, the research on composite welding fluid is less, and mainly by numerical simulation technology.

At present, the research on laser arc hybrid welding is mainly focused on the process, that is to say, the influence of different process parameters on the weld formation of hybrid welding is analyzed through the test method, so that the process can be applied to the actual production as soon as possible. However, the research on Composite welding is still less, because of the limitation of test conditions and the complexity of physical mechanism, the research on composite welding fluid is more It is rare and mainly relies on numerical simulation technology.
