| Abstract: | 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. |
