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.

Problems and issues in laser-arc hybrid welding
International Materials Reviews, 2009Abstract Hybrid welding, using the combination of a laser and an electrical arc, is designed to overcome problems commonly encountered during either laser or arc welding such as cracking, brittle phase formation and porosity. When placed in close contact with each other, the two heat sources interact in such a way as to produce a single high intensity ...

Temperature measurement of laser arc hybrid welding plasma
ICALEO 2003: 22nd International Congress on Laser Materials Processing and Laser Microfabrication, 2003Recently laser arc hybrid process is actively researched as a new heat source of welding. Laser arc hybrid welding is combination of laser characterized by the high energy density and electric arc characterized by the high energy efficiency. Metal is vaporized by irradiation of high power laser and this laser induced metal vapor makes path of electron ...

Mechanical properties of HSLA-65 hybrid laser arc welds
Canadian Metallurgical Quarterly, 2012desirable because they minimise HAZ softening and can tolerate gaps between the workpieces better than conventional laser welding. In this paper, the mechanical properties of hybrid laser arc welds, used to join 9?1 mm thick HSLA-65 plates in a single pass, were evaluated. Hardness maps indicated that softening did not occur in the HAZ.

Hybrid laser-arc welding of advanced high-strength steel
Journal of Materials Processing Technology, 2014Abstract This study investigated the synergetic effect between laser beam and electrical arc during hybrid welding by using a spectral diagnostic technique. The synergetic effect increased the energy density in the keyhole and deepened the weld penetration, resulting in a lower plasma electron temperature.

Evaluating Mechanical Properties of Hybrid Laser Arc Girth Welds
2010 8th International Pipeline Conference, Volume 2, 2010This paper presents the challenges and results associated with mechanical testing of overmatched X80 and X100 pipeline steel girth welds that were produced by Hybrid Laser Arc Welding (HLAW). The weld profile produced by this process is characterized as having a broad weld cap and a narrow leg, which traverses the through thickness direction.

Hybrid laser arc welding: State-of-art review
Optics & Laser Technology, 2018Abstract Hybrid laser arc welding simultaneously utilizes the arc welding and the laser welding, in a common interaction zone. The synergic effects of laser beam and eclectic arc in the same weld pool results in an increase of welding speed and penetration depth along with the enhancement of gap bridging capability and process stability.
