| Abstract: | MIG and laser hybrid welding technology of aluminum alloy for automobile is studied,rules on the influence of welding parameters to weld shape and the mutual effect between laser and arc are researched.The experiment showed that because of the common effect of laser and arc,weld penetration and welding speed were increased greatly and laser welding aluminum alloy with low powder was realized.Aluminum alloy weld line had good formation with MIG and laser hybrid welding,and production can be improved obviously. |
