摘　　要：通过对点焊喷溅形成机理的分析,结合镀锌钢板电阻点焊的特殊性,对白车身制造过程中产生点焊喷溅的影响因素进行了详细的分析。并结合生产现场的实际情况,对降低点焊喷溅的发生提出了相应的解决措施。对于提高车身表面质量、减低工人的劳动强度具有一定的实践意义。By analysing the mechanism of the spot welding splash and the particularity of the resistance spot welding galvanized steel sheet, the influence factors of spot welding splash during the manufacturing of the BIW (Body In White) are analyzed. To decrease the splash, the solution is put forward according to the production field, which can improve the surface quality of the body and decrease the labor intension.
