This study aims at examining dymamic deformation process on magnetic pressure seam welding of metal sheets and metal foils. As a result, collision behavior of magnetic pressure seam welding was able to be clarified to some extent by this study. 1) A collision point velocity between the metal sheet surfaces was very high at an initial collision point, but it decreased continuously during the welding. 2) When the gap length becomes narrow, collision point velocity was decreased early. 3) The collision angle between the metal plate surfaces was 0 degree at the initial collision point, but it increased continuously during the welding. 4) When the gap length becomes narrow, collision angle was increased slowly.
