焊接工艺方法,特别是对目前发展迅速的熔化极气体保护焊的研究发现,施焊过程中,电弧是否稳定,飞溅金属的大小和数量,熔池运动状态及随后的焊缝成形等等,都与螺丝端部熔化时形成的熔滴形状及其过渡状态有关。近三十多年来,各国都采用了高速摄影技术,将焊接电弧内部金属的熔化及熔滴的形成和过渡过程拍摄成高速影片,经过详尽的分析研究,大大改进了焊接工艺,并促使新的焊接工 Welding process, especially for the current rapid development of welding gas shield welding research found that the welding process, the arc is stable, the size and number of splashing metal, molten pool motion and subsequent weld formation, etc., are It is related to the shape of the drop formed when the screw tip melts and its transitional state. In recent thirty years, all countries have adopted high-speed photography technology, the welding arc internal metal melting and droplet formation and transition process of shooting into high-speed video, after detailed analysis and research, greatly improving the welding process, and to promote new Welder
