| 摘 要： | 在氦-氩混合气体保护条件下，对AZ31镁合金板材进行了TIC焊接，获得了表面光滑、无堆高和无变形等缺陷的焊缝。金相观察表明，和母材区相比，热影响区晶粒粗大，但焊缝区全部由均匀细小的等轴晶组成。

| Abstract: | The He-Ar mixed gas TIG welding for AZ31 magnesium alloy plate by was carried out. The surface of observed joint is smooth free from heap high and appearance defects. The microstructure in heat-affected area is coarser than that in matrix area. However, the microstructure in welded seam zone consists of fine equiaxed grains. |
