安慶市鋁合金外殼是一種常見的工業材料，廣泛應用于工業生產，如汽車制造、飛機制造、船舶制造、鋼鐵冶金、化工生產、電力工業、石油工業、煤炭工業、冶金工業、水泥工業、建筑工業等。鋁合金外殼具有良好的耐腐蝕性、耐磨損性、耐沖擊性、耐高溫性、耐低溫性、耐化學腐蝕性、耐久性、強度高、密度小、質量輕、吸聲性、導電性、熱導率高、反射率低、不易發生燃燒、無毒、無污染等優點。

　　With the rapid development of industry and technology, the demand for aluminum alloy shell is increasing day by day, and its application scope is also expanding. However, in actual production, due to the influence of various factors, the surface of aluminum alloy shell is easy to be corroded and damaged, which seriously affects the normal production and use of enterprises, and brings great economic losses. In view of this problem, the repair and improvement of aluminum alloy shell has become an important research direction in the field of surface engineering.

　　The repair technology of aluminum alloy shell mainly includes manual repair and automatic repair. The manual repair technology is suitable for repairing small defects, while the automatic repair technology is suitable for repairing large defects. In addition, the repair of aluminum alloy shell can be divided into cold repair and hot repair according to the repair temperature.

　　The cold repair technology of aluminum alloy shell is a kind of repair technology with low cost, simple operation and good repair effect, which is suitable for the repair of small defects. The cold repair technology of aluminum alloy shell mainly includes grinding and welding, which can be used to repair the surface defects of aluminum alloy shell, and improve the surface performance of aluminum alloy shell.

　　The hot repair technology of aluminum alloy shell is a kind of repair technology with high repair effect and good surface performance, which is suitable for the repair of large defects. The hot repair technology of aluminum alloy shell mainly includes gas welding, arc welding, laser welding and electron beam welding. The hot repair technology of aluminum alloy shell can not only repair the surface defects of aluminum alloy shell, but also improve the surface performance of aluminum alloy shell.

　　In order to further improve the repair effect of aluminum alloy shell, the surface of aluminum alloy shell is usually coated with a layer of protective film after repair. The commonly used protective film is anodic oxide film, which can improve the corrosion resistance, wear resistance and heat resistance of aluminum alloy shell.

　　安慶市鋁合金外殼的修復技術注重對生產過程中發生的損傷進行精細化修復，大大提高了產品的使用壽命，減少了企業的生產成本，提高了企業的經濟效益。
