Abstract: With the continuous development of digital technology, automation and intelligent control technology, traditional manufacturing industry gradually takes industrial robots as the core to carry out intelligent manufacturing. Because the parts of an aircraft storage box have the characteristics of large thin wall, various structures and different sizes, the current production methods mostly adopt the manual welding method of workers, which is inefficient. In order to solve the above difficulties, this paper analyzes the process based on the characteristics of the structural parts of a box-type product, designs the overall scheme of automatic welding, and evaluates the welding process. The welding verification is carried out for the welded structural parts. The welding quality is stable and consistent, and the production efficiency is improved. For the large batch of welded structural parts, the welding can be realized after fast clamping, and the welding efficiency is nearly 5 times higher than that of manual welding. The welding quality evaluation level II weld level reduces the labor intensity, and provides a reference for the introduction of automated welding technology in an industry.
