Analysis of Electrical Characteristics of Inter-wire Arc in Cross-Coupling Arc
Abstract As a new composite welding heat source introduced in recent years, the cross-coupling arc uses a non-consumable electrode arc (plasma arc) and a consumable electrode arc (inter-wire arc) in cross-coupling, in which the plasma arc is the main arc and the inter-wire arc is the vice arc, to re...
