Abstract. Magnetic pressure seam welding has attracted attention as a new joining method for aluminum thin plates. Magnetic pressure seam welding is a collision welding process, utilizing electromagnetic force as the acceleration mechanism. The electromagnetic seam welding is a method of abruptly adding a high density magnetic flux around a metal material and utilizing the generated electromagnetic force to deform the thin plate at high speed and pressure welding. This paper deal with the deformation behavior of parallel aluminum seam welded aluminum sheet. Numerical analysis of the dynamic deformation process of the metal plate is performed by the finite element method. The sample used for this analysis is assumed to be a thin plate made of aluminum (A1050-H24, width100mm, thickness 1mm) and composed of quadrilateral elements of plane strain. The experimental results show that the collision speed between the aluminum plates is sufficiently reproduced. The impact point velocity between the aluminum plate surfaces was very high at the initial collision point but decreased continuously during welding. It was also found that the smaller the gap is, the faster the collision point moving speed becomes.
