用09SiVL 代替16MnL 做汽车前后桥壳材料还是近年来的尝试,本文拟就我厂使用的实践,对其焊接工艺作一粗浅阐述。09SiVL 与16MnL 的化学成份,机械性能比较如表一、二所示从表中可以看出,09SiVL 与16MnL虽然含 C、Mn、Si、V 元素的量不同, Use 09SiVL instead of 16MnL to do front and rear axle housing materials or automobile in recent years, this paper intends to use our plant practice, a brief description of its welding process. 09SiVL and 16MnL chemical composition, mechanical properties as shown in Table 1 and 2 can be seen from the table, 09SiVL and 16MnL although containing C, Mn, Si, V elements of different amounts,
