CO_2气体保护焊焊补铸铁的焊缝组织与性能

The Structure and Properties of Welded Joint of Cast Iron by CO_2 Gas Shield Welding

以手弧焊和CO_2气体保护焊对铸铁进行焊接,结果表明:两种方法得到的接头强度相近,白口区宽度、硬度变化趋势基本相同。说明了以CO_2气体保护焊进行铸铁的焊补是可行的和经济的。

Arc welding and CO_2 gas shield welding were used for welding cast Iron. The result showed that strength, width of white iron area and hardness distribution of welded joint of CO_2 gas shield welding were little less than those of arc welding. Therefore, Welding in cast iron using CO_2 gas shield welding was available and it's cost was also lower.
