Hybrid welding with arc and laser beam

Science and Technology of Welding and Joining, 1999
This paper deals with a combination of two different welding processes, i.e. the synergic action of two different heat sources for fusion welding. The major part of the paper is focused on the combined action of a welding arc and a laser beam. The main advantage of the use of both heat sources is more efficient use of the energy supplied. With certain

Weld microstructure and shape of laser–arc hybrid welding

Science and Technology of Welding and Joining, 2008
A 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 ...

Welding properties of thin steel sheets by laser-arc hybrid welding: laser focused arc welding

SPIE Proceedings, 2003
Laser-arc hybrid welding combines the laser and arc welding processes to provide advantages not found in either. This process can weld lapped steel sheets that have a larger gap than is possible with laser welding. Blowholes form when lap-welding zinc-coated steel sheets because of the zinc that is vaporized.

Study of weld formation characteristics in laser-arc hybrid welding

International Journal of Modern Physics B, 2022
The 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

Hybrid Laser Arc Welding

2011
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).
