摘要
实验研究了不同激光能量输入情况下, 微米晶粒钢焊接接头各区域的硬度及尺寸。并对能量输人差别较大的不同焊接方法(激光、等离子弧)焊接微米晶粒钢的焊缝宏观形貌、晶粒度、硬度及冲击韧性进行了对比研究。表明激光焊接微米晶粒钢的优越性。
Abstract
The hardness and the dimension of micron-grained steel welding joint were studied with different laser energy inputting. The macroscopical configuration, grain size, hardness, and impact toughness of micron-grained steel joint that was acquired by different weld techniques with different energy inputting were investigated and compared. The research shows the micron-grained steel welded by laser has great superiority.
