$CO_2$ 용접기의 대전류영역에서의 단락이행 유도에 대한 용접성능개선에 관한 연구
A Study on Welding Perfomance Improvement using Short-Circuit Metal Transfer Induction on High-current $CO_2$ Arc Welding Machine
초록
The metal transfer of CO2 arc welding machine can be devided into short-circuit(low current) metal transfer. Especially in large crrent region, the main problem of CO2 arc welding machine is much spatter generation which is caused by mainly instant short-circuit matal transfer. So in this paper descrives new current control method in large current region, which can improve welding performance and lessen spatter generation. And as a result of experiment, the effect of proposed control method is demonstrated.
