Paper Abstract

In this paper, the electron rotating radius and the corresponding length above surface of the workpiece where the electron density is notably reduced are calculated on the condition of adding magnetic field in laser welding according to the temperature of plasma and the average velocity of electron motion. The experiments results indicate that on the set condition, the weld area is increased by 18% with the weld penetration and the melting efficiency being increased by 22% and 13% respectively when the magnetic flux density added is set at 96 mT.
