Magnetic pressure seam welding of metal sheets and metal foils

本研究旨在研究金属薄板与金属箔磁压缝焊的动态变形过程。结果表明，本研究能够在一定程度上阐明磁压缝焊过程中的碰撞行为。1)金属板材表面之间的碰撞点速度在最初的碰撞点很高，但在焊接过程中不断下降。2)当间隙变窄时，碰撞点速度较早降低。3)金属板材表面的碰撞角在初始碰撞点为0度，但在焊接过程中逐渐增大。4)当间隙变窄时，碰撞角缓慢增大。

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.
