Numerical simulation of an external cusp magnetic field on the welding arc

A controlled welding arc is an up-and-coming research area for high-efficiency and high-precision wire arc additive manufacturing.This numerical simulation demonstrates that an alternating external cusp magnetic field (ECMF) can compress elbeco adu ripstop pants the arc.This is the result of the reversal of the Lorentz force direction caused by the reversal of the magnetic poles.

The simulation results show that the solenoid current directly affects the arc section ellipticity, and the alternating frequency affects the ar-13995n arc contraction.The high-speed photos demonstrate the feasibility of ECMF.
