ABSTRACT

Aluminum alloys are widely used in various structural constructions due to their excellent metal properties, and there are characteristics of difficulty in assembly. Based on this, the paper analyzes the influence of welding tooling and process on the welding performance of aluminum alloy, selects the surface positioning method, designs various types of splint, and completes the design of box welding tooling. On this basis, vacuum electron beam welding is used to complete the tailor welding of the chassis through strict process measures, and the weld seam with the aspect ratio meets the requirements is obtained, which ensures the integrity of the chassis structure.
