Embodiment 1
[0028] Step 1: Before welding, after grinding and cleaning the surface of 6061 aluminum alloy, fix it on the workpiece loading platform at the bottom of the welding vacuum box with a clamp, and then pump the air pressure in the welding box to 10Pa through a molecular pump.
[0029] Step 2: Use a fixture to rigidly fix the welding laser head and the arc welding torch to ensure that the end of the welding wire is located at the focus of the laser beam, and the inclination angle between the laser beam and the arc welding torch is 45°.
[0030] Step 3: After the preparation of the laser-arc hybrid welding system is completed, set the laser power to 2000W, the defocus to 0mm, the moving speed of the workpiece loading table to 25mm / s, the wire feeding speed to 0.2mm / s, and the welding current to 100A, then Perform laser-arc hybrid welding.
[0031] After the welding is completed, the surface of the test piece is smooth and uniform, and there are no defects such as pores and cracks i...
