Influence of waveforms on Laser-MIG hybrid welding characteristics of 5052 aluminum alloy assisted by magnetic field

, 2020
Laser-MIG hybrid welding of 5052 aluminum alloy assisted by magnetic field with three waveforms was performed. The results showed that compared to that without a magnetic field (NMF), the weld depth was increased by 46.3%, 45.1% and 22.4%, respectively ...

Hybrid laser-MIG keyhole welding of thick steel/Al butt joints

ICALEO 2018: 37th International Congress on Applications of Lasers & Electro-Optics, 2018
Dissimilar joining of steel/Al joints has become more and more significant in industrial applications with particular weight saving interest. However, directly welding of steel/Al joints even in thin thickness is very difficult. In the present study, the hybrid laser-MIG source focused on the steel side in keyhole mode was introduced to weld steel/Al ...

Mechanical properties of a dissimilar aluminum alloy joint welded by hybrid laser–MIG welding

International Journal of Modern Physics B, 2017
Two dissimilar Al alloys, 5083-H111 and 6005A-T6, were joined by hybrid laser–MIG welding method. Mechanical properties of the welded joint were investigated and compared. The results show that the tensile strength of the dissimilar joint is 219.8 MPa, 11.7% higher than that of 6005A-T5 joint.

Double-sided hybrid laser-MIG welding plus MIG welding of 30-mm-thick aluminium alloy

The International Journal of Advanced Manufacturing Technology, 2018
Hybrid laser-MIG (metal inert gas) welding has not been extensively applied in welding of aluminium alloy with thickness more than 10 mm because of the existence of weld defects and low joint strength. In this study, an original hybrid laser-MIG welding plus MIG welding process was developed.
