本文从理论上解决了冷压滚焊技术参数的几个关键性问题,即冷压滚焊的变形特征、焊接压力的变化规律等,为焊机和压轮的设计及焊接工艺的制定提供了理论依据。本文还介绍了冷压滚焊用于制造单管中同轴电缆的技术。与TIG 焊相比,冷压滚焊具有较高的生产率,并且既经济又可靠。 This article solves several key problems in the technical parameters of cold-rolled seam welding in theory, that is, the deformation characteristics of cold-rolled seam welding, the variation of welding pressure and so on, which provide the design of welding machine and pressure roller and the formulation of welding process Theoretical basis. This article also describes cold-rolled seam welding for the manufacture of coaxial tubes in single-tube technology. Compared with TIG welding, cold rolled seam welding has high productivity and is both economical and reliable.
