Abstract

The invention relates to a method for welding aluminum alloy thin plates, which is characterized in that: step 1, providing a first workpiece and a second workpiece that need to be welded by overlapping; step 2, accurately overlapping and clamping the first workpiece and the second workpiece; Step 3, provide the third workpiece, the third workpiece is located directly above the second workpiece; step 4, provide the laser cutting system; step 5, provide the air column spray gun; step 6, provide the ultrasonic vibration device; step 7, start the laser cutting system , the laser beam formed by focusing the laser cutting head vertically irradiates the upper surface of the third workpiece; step 8, start the air column spray gun, and the air column spray gun sprays inert gas to act on the metal droplets formed by laser cutting; step 9, start the ultrasonic generating device; Step 10, completing the welding process. Compared with the prior art, the invention has good welding effect.

Description

technical field [0001] The invention relates to the field of welding, in particular to an aluminum alloy sheet welding method. Background technique [0002] In automobile production, in order to reduce the weight of the vehicle without too much impact on the driving performance of the automobile, reducing the weight of the automobile except the chassis has always been the direction that those skilled in the art are working hard on. Because of the light weight, certain plasticity and surface corrosion resistance of aluminum alloy, this technology has been used to replace the usual thin steel plate to process the body. However, a serious defect of this type of aluminum alloy is that it is prone to deflection and deformation due to its large thermal conductivity and linear expansion coefficient during welding during processing. Therefore, at present, the welding of aluminum alloy sheets is performed under the fixation of large fixtures, such as commonly used piano-type welding...
