| Abstract: | 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. |
