摘　　要：采用功率为400 W的Nd:YAG激光器对铜进行激光钎焊。通过优化焊接工艺参数,获得了成形良好的焊接接头。通过填充不锈钢钎料,实现小功率激光器焊接较厚紫铜的目的。焊接接头的拉力测试结果表明,铜钎焊接头的抗拉强度可达母材的80%以上。Utilized 400 watt Nd：YAG laser with the wavelength of 1. 06 μm for laser brazing of copper. By improving the process parameter,achieved well joint. Through the stainless steel - base brazing,can improved the absorption of laser,then actualized welding copper by the low power laser. The testing result of showed that the joints of copper laser brazing is 80% of base material.
