3.The results show that the zinc coating can stabilize the arc as the plasma cathode during welding with lower current,but with the rise of the welding current the zinc coating will vaporize acutely,which make the arc edge ascend,and the contact area between the arc and the workpiece is lessened to reduce theheat input,which reduces the thickness of the interfacial brittle compounds.结果表明,小电流焊接时,镀锌层可以作为等离子体阴极,起到稳定电弧的作用,而在无镀锌层条件下,电弧的阴极斑点不停地跳跃,电弧极其不稳;随着焊接电流的增大,在镀锌钢板上焊接时,由于镀锌层的蒸发变得十分剧烈,这种蒸发行为也使得在镀锌钢板上焊接时的电弧的边缘上翘,减小了电弧与工件的接触面积,进而降低了焊接热输入,减小了界面脆性化合物层的厚度。
