Abstract：

During the electromagnetic forming process of pipe fittings，the success rate of electromagnetic forming is low due to the problems of excessive voltage causing the fracture of pipe fittings and the conversion of electrical energy into unnecessary energy in the forms of light and heat leading to the uneven deformation amount or forming. In order to improve the forming quality and forming efficiency of small diameter pipe fittings, the electromagnetic forming process was optimized by the response surface optimization and the central composite test design approach. Furthermore, using the central composite test approuch, taking loading voltage, length and material of pipe fittings as factors, setting the loading voltage of 5500, 6500 and 7500 V respectively, and using the small diameter pipe fittings with the length of 18, 45 and 65 cm respectively and the materials such as 3003, 6063 and 2024 aluminum alloys, by fitting the regression equation and variance analysis, the optimum solution was obtained as the material of 6063 aluminum alloy, the pipe fittings length of 52 cm and the loading voltage of 6000 V.
