Abstract

Magnetic pulse welding realizes solid-state connection through a high-speed collision of materials, which can effectively overcome the welding difficulties of light metal materials. In the magnetic pulse welding system, in order to improve the welding efficiency, a field shaper is usually applied between the multi-turn coil and the workpiece to concentrate the magnetic field in the welding area, thereby improving the electromagnetic force. However, a large number of researchers are currently on the tube-welded field shaper, and very few researchers have studied the structure of the plate-welded field shaper. Therefore, this paper proposed a new field shaper for plate welding. The effect of the structure parameter of the field shaper on the magnetic field and electromagnetic force on the aluminum plate was analyzed in the COMSOL multiphysics software. The optimal structure parameters of the field shaper were selected. The plastic deformation and the generation of jets under different voltages and the welding of the same/dissimilar metal materials at different standoff distances were studied experimentally, which verifies the feasibility of the new field shaper.

设计适用于板材的现场成型机，开展异种材料焊接实验研究

磁脉冲焊接通过材料的高速碰撞实现固态连接，可有效克服轻金属材料的焊接难题。在磁脉冲焊接系统中，为了提高焊接效率，通常会在多圈线圈和工件之间加装一个磁场整形器，将磁场集中在焊接区域，从而提高电磁力。然而，目前大量研究人员都在研究管状焊接场整形器，很少有研究人员对板状焊接场整形器的结构进行研究。因此，本文提出了一种用于板材焊接的新型场整形器。在 COMSOL 多物理场软件中分析了场整形器的结构参数对铝板上磁场和电磁力的影响。选择了最佳的场整形器结构参数。实验研究了不同电压下的塑性变形和射流的产生，以及不同间距下相同/异种金属材料的焊接情况，验证了新型场整形器的可行性。
