Study of weld formation characteristics in laser-arc hybrid welding
International Journal of Modern Physics B, 2022The laser-arc hybrid welding was carried out on the marine-use steel, and the effects of primary parameters on weld behavior were investigated. The results show that the weld penetration increased gradually with the increase of laser power. Meanwhile, superior weld formation, penetration and reinforcement were achieved when laser and wire distance was

Weld microstructure and shape of laser–arc hybrid welding
Science and Technology of Welding and Joining, 2008A series of CO2 laser–metal inert gas arc hybrid welding experiment was carried out to investigate the effects of laser/arc energy ratio and groove parameters on the shape and microstructure of hybrid weld. The results showed that increasing arc current and groove cross-section area can reduce dimension difference of laser zone and arc zone by ...

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).

Arc Welding and Hybrid Laser-Arc Welding
2009Laser-arc hybrid welding has developed into a viable industrial technology in recent years, and is attracting increasing commercial interest. The physics of the underlying interactions is quite complex. In order to explore the relationships involved, it is useful to consider important aspects of laser and arc welding separately.

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.
