HYBRIDLASERARCWELDING (HLAW), also known as laser hybrid welding or simply hybrid welding, is a metal joining process that combines laser beam welding (LBW) and arc welding in the same weld pool. The concept of HLAW was first introduced in the 1970s as “arc-augmented laser welding” that combined LBW with gas tungsten arc welding (GTAW) (Ref 1).

Weld characterization of laser arc hybrid welding of pure copper
The International Journal of Advanced Manufacturing Technology, 2017A series of experiments of high-power fiber laser-arc hybrid welding of pure copper was carried out. It could be seen that the microstructure of weld metal was obviously coarsened, and the columnar grain spacing at fusion zone and the massive grain size at heat-affected zone were both linearly increased with the increase of heat input.
