Due to pulse YAG laser used for material processing with high power density, focusing spot small, small heat affected area, etc., and have been applied more and more, especially in the fine processing. This paper on the theory and practice of two aspects to do a lot of analysis and experimental, solved the part of the problem, and promote the development of the laser welding process. First of all from the interaction of laser and material physical basis, establish and simplified the sandwich plate heating model, from theory to find out the best coating thickness. Then mainly analyzes the influence of various parameters of laser welding quality, optimizing the parameter combination, make welding to achieve the best effect. The YAG laser bridge wire welding experiment, through the experiment to influence the laser welding quality parameters of the correctness of the analysis, and the improvement in the process of laser cladding technology, accelerate the laser welding technology of automation process, has great application value of popularization.
