摘　　要：以0.19~0.21mm镀铬薄板作为研究对象,从理论和实验两个方面研究验证YAG激光不同光斑与焦距对焊接速度及质量的影响。实验结果表明,采用柱状光斑或多点光斑与采用—个光斑形式进行焊接相比,同条件前提下焊接速度和焊接质量均有所提高。因此,进行薄板激光焊接作业,要提高焊接质量或焊接速度,宜采取柱状光斑或多点光斑形式。In this paper,0.19 to 0.21 mm chrome plated she et is taken as the research object,and the influence of YAG la sesrpot and focal length on the welding speed and quality is studied ofmr two aspects of theory and experiment.The experimental result s show that the welding speed and welding quality of the cylindcrail spot or multi spot spot are improved compared with that of tshpeo t spot.Therefore,in order to improve the quality of welding otrh e speed of welding,it is necessary to take the form of cylindarli cor multi spot light spot to improve the welding quality or speed of welding.
