Problems and Issues in Laser-Arc Hybrid Welding

International Materials Reviews, 2009
Abstract 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 ...

Laser-Arc Hybrid Welding

Solid State Phenomena, 2007
Hybrid welding of stainless steels or aluminum alloys was performed using the heat sources of YAG laser and TIG, or YAG laser and MIG, respectively. The effects of welding conditions and melt flows on penetration depth, weld bead geometry and bubble/porosity formation were investigated with X-ray transmission real-time observation method.

Interaction mechanisms in hybrid laser arc welding

ICALEO 2014: 33nd International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2014
Achievable benefits in hybrid laser-arc welding are closely related to suitable parameter settings. Basic optimizations consequently need a profound understanding of the relevance of involved interaction mechanisms. These are however differently evaluated and discussed in literature.
