Abstract: The test uses a resistance welding machine to implement resistance spot welding of 6061-T6 aluminum alloy thin plate for automobile body and obtains the welding process parameters of resistance spot welding through the test. Using an orthogonal test scheme and extreme difference analysis method to test and further optimize the resistance welding process parameters, after lap resistance spot welding of a 6061-T6 aluminum alloy thin plate with a thickness of 2 mm, we analyze the welding appearance and complete the tensile test. The test results show that when the welding current is 60 KA, the welding pressure is 0.63 MPa, the thickness of the plate is 2.00 mm, the spot weld joints obtained from the specimen have no obvious defects, better molding, good welding quality and appearance, and its tensile shear value is 5.583 KN at maximum.
