Review on Weld Formation and Defect Control of Energy Field Assisted Laser Welding
The laser welding is a high-efficiency joining technique with high energy density
narrow heat affected zone and small workpiece deformation. However
problems still exist in laser welding
such as high cooling speed
cracks
pores
etc. Spatters and pores were effectively inhibited by adding suitable gas or using oscillating laser. The joint defect was reduced and the welding process stability was effectively improved by using arc assisted laser welding. Laser welding assisted by ultrasonic
magnetic and electric fields can improve joint performance by refining grain
reducing element segregation and crack sensitivity. The review on laser welding was summarized from three perspectives
namely process optimization
auxiliary heat source and auxiliary energy field. Finally
problems existing in the research of energy field assisted laser welding were analyzed and its development prospect was forecasted.
