Molten pool morphology and microstructure evolution of WAAM Ti6Al4V under in-situ electropulsing

Molten pool morphology and microstructure evolution of WAAM Ti6Al4V under in-situ electropulsing

When the pulsed current is used to assist the WAAM process, the entire working area is in an external magnetic field due to electromagnetic coupling. The stable arc is deflected by the Lorentz force, which stirs the molten pool and accelerates the fluidity of the melt. Through the high-speed camera...
