摘　　要：研究了扁钢带直流电阻对焊工艺，分析了变形机理．试验结果表明，增大位移门槛电压值或者减小预压力，可增大塑性金属的变形程度，这有利于将杂质从接合界面挤出．The technology of DC upset butt welding on A3 flat steel strip is investigated , and the deformation mechanism of butt joint is analysed. The experimental results show that the deformation of plastic metal may be increasing the displacement threshold voltage or by decreasing initial pressure. This will benefit the expelling of interfacial contaminant.
