摘要

在铝合金激光深熔焊接的基础上,研究了修饰焊对激光深熔焊缝成形的影响。结果表明:激光修饰焊不仅可以显著改善铝合金焊缝咬边、下塌等成形不良缺陷,减小焊缝表层气孔;还可以细化接头组织,在一定程度上提高接头的强度和塑性。表明了激光修饰焊是强化铝合金激光焊接头的有效方法。

Abstract

Effects of modification welding on formation of laser full-penetration weld are studied, which is based on the laser welding process of aluminum alloy. The results show that the welding defects (such as undercut, slump and so on) could be improved obviously, and the microstructure of joint by modification welding could be finer than that of joint only by laser welding. Besides, the strength and toughness of joint could also be increased to some extent by the modification welding after laser full-penetration welding. Therefore, the laser modification welding is an effective method in order to strengthen the laser welding joint.
