Combined stacking device for resistance spot welding

The present disclosure provides a combination stacking device with perforated interlayers for resistance spot welding. The apparatus includes a first metal plate made of a first material and a second metal plate made of a second material. The device also includes a perforated interlayer disposed between the first metal layer and the second metal layer. The perforated interlayer is made of one of the first and second materials. The perforated interlayer has a plurality of perforations formed therethrough. Each perforation has a perforation size of between about 0.1 mm and about 3 mm. 本公开提供了一种用于电阻点焊的具有穿孔夹层的组合堆垛装置。该装置包括由第一材料制成的第一金属板和由第二材料制成的第二金属板。该装置还包括设置在第一金属层和第二金属层之间的穿孔夹层。穿孔夹层由第一和第二材料中的一种制成。穿孔夹层具有穿过其形成的多个穿孔。每个穿孔的穿孔尺寸在约0.1mm到约3mm之间。
