Abstract

The invention relates to an automatic welding device achieving low deformation for a circular seam of a thin-wall aluminum alloy oil tank. The automatic welding device is used for annularly welding tank body end plates and a tank body plate into a whole. The peripheral areas of the weld joint before and after welding are cooled at the same time, the cooling speed of base metal around the weld joint is increased, and deformation before and after welding is reduced. A robot cooperative control mode is adopted, the accessibility of the welding position is guaranteed while the cooling effect is guaranteed, and full-automatic welding of peripheral weld joints can be achieved. When the device is used for welding the thin-wall aluminum alloy oil tank, the tack welding procedure can be omitted, and the welding efficiency is improved by 20%-40%. By means of the automatic welding device, welding manufacturing of thin-wall aluminum alloy oil tanks of different sizes can be achieved, automatic high-precision welding of circular seams of various aluminum alloy oil tanks is achieved, and therefore welding stability is improved, and robot welding of thin-wall components can be efficiently and rapidly achieved.

Description

technical field [0001] The invention belongs to the technical field of circular seam welding, and in particular relates to an automatic welding device and method for low deformation of the circular seam of a thin-walled aluminum alloy fuel tank. Background technique [0002] Compared with steel materials, aluminum alloy components have stronger heat transfer characteristics and larger expansion coefficients. The welding deformation in the actual welding process is a problem that needs to be considered and solved. For aluminum alloy thin plates, the welding deformation is larger. How to solve the deformation problem is the key to automatic welding and the basis for improving the efficiency of robotic welding of thin plate components. [0003] The welding deformation of aluminum alloy components mainly depends on the size of the molten pool and the heat input per unit time during the welding process. A large amount of heat conduction in a short period of time will easily lead...
