摘　　要：马钢第一钢轧总厂冷轧1#镀锌生产线采用三菱公司的窄缝搭接焊机(MSW)。该焊机是为了实现连续生产对前、后卷带钢进行焊接。系统根据工艺要求主要涉及焊接电流、速度、压力等主要参数的控制,本文阐述了PWM技术在该系统上对焊接电流的控制。A mash seam welder (MSW) from Mitsubishi is installed at the NO.1 CGL of Masteel's cold rolling mill to realize semi-endless production by welding the consecutive coils together. Some important parameters, such as welding current, welding speed and welding pressure, must be controlled according to process requirements. PWM technology for the control of MSW welding current is expounded in the paper.
