磁场辅助电弧增材制造边缘焊道流淌抑制研究
Research on suppression of edge weld flow in magnetic field-assisted arc additive manufacturing
摘要
Abstract
To investigate the impact of a longitudinal magnetic field on the flow of edge weld beads in arc additive manufacturing,a comprehensive study was presented combining simulation and experimental research on arc additive manufacturing augmented by a longitudinal magnetic field.The influence of the longitudinal magnetic field on the morphology of weld beads was compared and analyzed,and the effectiveness of using a longitudinal magnetic field to suppress the flow of edge weld beads in arc additive manufacturing was explored.Experimental results show that the longitudinal magnetic field generates Lorentz force by interacting with the welding current to stir the molten pool,which can promote the circumferential flow of the molten pool;The longitudinal magnetic field can significantly affect the flow mode of the molten pool and change the symmetry of the weld bead morphology;The longitudinal magnetic field can significantly suppress the overflow and flow of the molten pool during 1.67 times the mass input per unit time(i.e.60％normal walking speed deposition).关键词
