HYBRIDIZATION OF LASER WELDING
Transport engineering, 2022The paper objective is to study a hybrid welding process based on the combination of two methods: laser and plasma ones. The combination of two different types of welding is a promising way to detect and then eliminate the defects of each of them.

Welding phenomena and weld penetration during laser or hybrid welding
PICALO 2010: 4th Pacific International Conference on Laser Materials Processing, Micro, Nano and Ultrafast Fabrication, 2010Laser and hybrid welding phenomena for the production of sound and deep welds are described from the observation results of plume behavior, plume-laser interaction, keyhole behavior and melt flows on the surface and inside the molten pool through high speed video cameras and X-ray transmission imaging system.

ICALEO 2015: 34th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2015
The welding of steel with large plate thicknesses gains more and more in importance for the structural steelwork engineering (e.g. pipe- or crane building). Nowadays those welding tasks are performed by a time-consuming conventionally submerged-arc welding process.

Hybrid laser welding techniques for enhanced welding efficiency
ICALEO '96: Proceedings of the Laser Materials Processing Conference, 1996One of the remarkable characteristics of the laser beam welding process is its thin deep welding seam. This thin seam is produced as a result of the high welding speed and the low heat input, leading to a low distortion. However, the overall electrical efficiency of a CO2-laser is in the range of 5-7% and the efficiency of a Nd:YAG-laser is only ...

Modeling of Weld Beads for Laser-GMA Hybrid Welding
Key Engineering Materials, 2007For laser-GMA hybrid welds, the relationship between the process parameters and bead shapes was investigated by using the experimental design and the non-linear regression. The weld beads were fitted by two quadratic functions. By the statistical analysis, the primary bead was mainly affected by GMA welding parameters and the root bead was mainly by ...
