摘要:

本文通过电弧-激光双热源相互作用规律的研究,提出了一种崭新的焊接方法电弧-激光点焊。实验证明,这种新工艺可以焊接现有点焊方法难以焊接的点焊接头,例如可点焊厚度比相差很大且上板较厚的搭接接头铜,铝等良导体的接头。

Abstract:

A new welding method-arc-laser spot welding, based on the study of the interaction of arc and laser dual power source, is proposed in this paper. Experiments have proved that this new method can weld the joints which are difficult to be welded by ordinary spot welding. For instance, it can spot weld the lap joints of thicker upper plates with large plate thickness ratio as well as joints made up of copper, aluminum and other highly conductive materials.
