Outline
With the aluminum alloy door of passenger car as the research object, the laser wire filling welding process and welding quality of aluminum alloy sheet are studied through comprehensive application of simulation and process test. The optimal process parameters suitable for laser wire filling welding of aluminum alloy door are obtained by judging the forming quality and mechanical properties of the weld after welding. Using this parameter, the laser wire filling welding of the inner plate assembly of the aluminum door is prototyped and a better welding quality is achieved. The results show that for the laser wire filling lap welding of 5182 aluminum plate and 6016 aluminum plate with thickness of 1.5 mm, better weld forming quality and mechanical properties can be obtained with the following process parameters: 2 600 W laser power, 2.5 m/min welding speed and 7 m/min wire feeding speed, and can satisfy the welding quality requirements of the actual aluminum door inner plate assembly.
