通过使用光纤激光矩形光斑,对异种金属AA6061铝合金和镀锌钢完成熔钎焊接,研究了接头的微观组织和力学性能。结果表明,焊缝较为饱满,未出现气孔、裂纹等缺陷。焊接接头的机械抗力可达到152 N/mm2。
The fusion welding of dissimilar metal AA6061 aluminum alloy and galvanized steel was completed by using the rectangular laser spot of fiber laser. The microstructure and mechanical properties of the joints were studied. The results show that the weld is full, no defects such as pores and cracks appear. Mechanical resistance of welded joints up to 152 N / mm2.
