Effects of welding parameters on melting energy of CO2 laser–GMA hybrid welding
Ming Gao,Xiaoyan Zeng,Q. W. Hu +2 more
TL;DR: A series of CO2 laser-gas metal arc (GMA) hybrid welding experiments were carried out on the mild steel workpiece to investigate the effects of the welding parameters, such as laser power, arc current and the distance between laser and arc D LA, on the melting energy as discussed by the authors.
Journal ArticleDOI
Microstructure and mechanical properties of laser-MIG hybrid welding of 1420 Al-Li alloy.
TL;DR: In this article, the microstructure and mechanical properties of 1420 aluminum-lithium (Al-Li) alloy joints before and after heat treatment by CO2 laser-metal inter gas (MIG) hybrid welding were investigated.
Journal ArticleDOI
Study of porosity suppression in oscillating laser-MIG hybrid welding of AA6082 aluminum alloy
TL;DR: In this article, the effect of beam oscillation on porosity formation and suppression was studied by observing keyhole behavior via a "sandwich" high-speed video method, and it was found that porosity suppression depended on three reasons: high-frequency oscillating keyhole can enlarge the diameter of keyhole and improve keyhole stability.
Journal ArticleDOI
Laser-TIG hybrid welding of ultra-fine grained steel
TL;DR: For improving the weldability of ultra-fine grained (UFG) steel, detailed experiments of laser-tungsten inert gas (TIG) hybrid welding were carried out on this material to investigate the effects of welding parameters on weld shape, microstructure, grain growth in heat-affected zone (HAZ) and mechanical performance.
Journal ArticleDOI
Effects of circular oscillating beam on heat transfer and melt flow of laser melting pool
Chen Zhang,Xinwei Li,Ming Gao +2 more
TL;DR: In this paper, the basic mechanism during circular oscillating laser welding process was studied by computational fluid dynamics method and the results showed that the circular oscillation frequency and amplitude reduced the peak temperature and temperature gradient and formed a new vortex in the melt pool.
