Research on Technology of Welding Aluminum Foil in Pressure Vessel Based on Ultrasonic Rolling Welding

Abstract:

For solving the problems of low bonding strength of anticorrosive layer inside the pressure vessel, the technology of ultrasonic continuous welding applied in aluminum alloy foil is researched in this paper. The technological parameters which affect the welding quality most are analyzed. Through the finite element simulation, the stress and temperature distribution of metal layer and welding head during the welding process are analyzed. The influence of important parameters such as welding pressure and thickness of metal layer on welding quality are studied. The optimal combination of key process parameters such as welding speed, welding pressure and thickness of metal layer are discussed by orthogonal test. The results show that the bonding strength at the weld can reach the tensile strength of the metal itself, and is also qualified to the design expectation.
