The influence of the pre-placed powder layers on the morphology, microscopic characteristics and microhardness of Ti-6Al-4V/WC MMC coatings during laser cladding
TL;DR: In this paper, powder-presetting laser cladding technology was employed to fabricate WC particles reinforced MMC coatings applying pre-placed pure WC powder layers and Ti-6Al-4V/WC powder layers, respectively.
Journal ArticleDOI
Influence of magnetic field orientation on molten pool dynamics during magnet-assisted laser butt welding of thick aluminum alloy plates
TL;DR: In this article, a multi-physics coupling model was developed and numerically solved by considering the electromagnetic interaction between static magnetic field and magnetofluid, and the dynamic and electromagnetic information within the weld pool were predicted and comparatively analyzed.
Journal ArticleDOI
Influence of laser power on molten pool flow field of laser-MIG hybrid welded Invar alloy
TL;DR: In this paper, the effect of laser power on the flow field was investigated under the condition of considering the keyhole and molten pool dynamic behaviors in Laser-MIG hybrid welding.
Journal ArticleDOI
Temperature field simulation and grain morphology on laser welding-brazing between Ti-6Al-4V and 1050 aluminum alloy
TL;DR: In this paper, a 3D finite element model is developed to calculate the temperature field in the laser welding-brazing (LWB) process with a combined Gaussian heat source model.
Journal ArticleDOI
The porosity formation mechanism in the laser-MIG hybrid welded joint of Invar alloy
TL;DR: In this article, the porosity formation mechanism in the laser-metal inter gas (MIG) multi-layer hybrid welded (HW) joint of 19.05mm thick Invar alloy is investigated.
