摘　　要：用激光焊接的方法将铝和不锈钢进行焊接,观察了焊接区域的显微组织,分析了显微组织的形成机理。结果表明:两种金属都含有对方的元素,激光焊接得到了更为细小、均匀的组织成分,具有可焊性。Aluminum and stainless steel were welded by laser, the microstructure of the weld area was observed, and the forming mechanism of the microstructure was analyzed. The result shows that both of metals contain each other, and the laser welding achieves smaller and evener microstructure.

关 键 词：激光焊接 显微组织 不锈钢+铝
