Analysis of Electrical Characteristics of Inter-wire Arc in Cross-Coupling Arc

Chinese Journal of Mechanical Engineering, 2019
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 ...

Arc Plasma Propagation and Arc Current Profiles [PDF]

IEEE Transactions on Plasma Science, 2019
When electrical arcs occur in space, a plasma expands away from the arc-site, neutralizing adjacent surfaces (a current), and causing a current to be produced at the arc-site (source of neutralization current). The speed of this plasma expansion depends on the plasma species, which in turn depend on the ionizable materials near the initial ...
