This paper deals with dynamic deformation process on magnetic pressure seam welding of aluminum sheets. Numerical analysis of the dynamic deformation process of the aluminum sheets is made by a finite element method. In this analysis, the metal sheets (100 mm width, 1 mm thickness) are modeled with plane-strain quadrilateral elements. A collision point velocity between the aluminum sheet surfaces was very high at an initial collision point, but it decreased continuously during the welding. A collision angle between the aluminum sheet surfaces was 0 degree at an initial collision point, but it increased continuously during the welding. The collision angle in a double-sided magnetic pressure seam welding process increased more quickly than that in a single-sided magnetic pressure seam welding process.
