Aluminum alloy die-casting parts are prone to adhesion of a large amount of dust and moisture on their surface due to their activity and susceptibility to oxidation during operation. Therefore, during the welding process, things attached to the surface are easily left on the surface of the aluminum alloy with laser welding, thereby affecting the quality and welding effect of the aluminum alloy. Therefore, before welding, it is necessary to clean the surface of the aluminum alloy and remove any oil stains on the surface. At the same time, it is necessary to prevent oxidation during welding from causing stable threats such as explosions, and to thoroughly clean the oxide film on the surface.

Quality of use refers to the long-term working ability of castings under different conditions, including wear resistance, resistance to cold and heat shock, fatigue, shock absorption, and other performance, as well as cutting ability, weldability, and other process properties. In casting production, it is necessary to control and inspect the quality of castings. At first, it is necessary to establish process rules and technical conditions for controlling and inspecting each specific product from raw materials and auxiliary materials. Strictly control and inspect each process in accordance with the process rules and technical conditions. Then conduct quality inspection on the finished castings. Proper testing methods and appropriate testing personnel should be equipped. Generally, for the appearance quality of castings, a comparison sample can be used to determine the surface roughness of castings; Tiny cracks on the surface can be inspected using staining and magnetic particle methods. For the internal quality of castings, audio, special, eddy current, X-ray, and γ Radiography and other methods are used for inspection and judgment.
