In this paper, a number of factors influencing the joining property of sheets welded by a magnetic pulse welding are described. An electromagnetic force deforms a moving sheet, and the height of the sheet is governed by both the force and the properties of the sheet. Some information obtained from the first collision time is very useful, so two sheets with a gap can be joined with each other after the first collision. The relationship between the collision time and the gap length for an aluminum sheet is examined by 2.0kJ discharge energy experiments, and an approximation curve of this relationship is drawn. The velocity of the moving sheet is found by differentiation of the curve. The relationship between shearing load with the welded sheet and the gap length is also examined. Similar results have also been obtained for a copper sheet, and the relationship between the shearing load and the collision velocity has been shown for two materials. It has been clarified that the shearing load is distributed into three areas depending on the collision velocity. Therefore, the collision velocity is the main factor influencing the joining property of welded sheets. It has also been clarified that another influencing factor is the first collision time.
