【Abstract】 A new Short-circuit CO₂ welding process has been studied,by which the maxi- mum short-circuit peak current is limited and the arcing current is Increased with a special controller.It is proved that the new control method can obviously reduce the spattering loss,improve the weld formation and broaden the criteria of the optimum welding conditions.更多还原
