Fiber laser-MIG hybrid welding of 5 mm 5083 aluminum alloy

Journal of Materials Processing Technology, 2016
Abstract Aluminum and its alloys are difficult to weld due to their specific characteristics. New joining methods such as high power fiber laser-MIG can provide higher overall productivity compared to the arc welding or laser beam welding. There is huge lack of information on how the specific welding parameters in laser-arc hybrid welding affect ...

Analysis of weld pool dynamic during stationary laser–MIG hybrid welding

The International Journal of Advanced Manufacturing Technology, 2009
A mathematical model was established to simulate the weld pool development and dynamic process in stationary laser–metal inert gas (MIG) hybrid welding. Surface tension and buoyancy were considered to calculate liquid metal flow pattern; moreover, typical phenomena of MIG welding such as filler droplets impinging weld pool, electromagnetic force in the
