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.

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

Interaction mechanisms in hybrid laser arc welding
ICALEO 2014: 33nd International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2014Achievable 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.

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 ...

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.
