Quantitative analysis of synergic effects during laser-arc hybrid welding of AZ31 magnesium alloy
TL;DR: In this paper, a dimensionless parameter, i.e., arc current increment (ψ), was proposed to quantitatively characterize the synergic effects by counting the difference in the average arc current between the hybrid welding and metal inert gas welding, and the stabilization mechanisms of both the burning and droplet transfer of the magnesium arc were discussed in terms of the calculated ψ.
