在国内外铝外导体中同轴电缆的生产中,一般都采用氩弧焊。但氩弧焊是一种需要热源的焊接方法,有可能烧坏电缆的竹节带,影响其电气性能;而且焊接规范中影响质量的可变参数多,都必须严格控制,否则,焊缝易产生缺陷。国内有些单位,为获 In the domestic and foreign aluminum conductor in the production of coaxial cable, are generally used TIG. However, TIG welding is a welding method that requires heat source and may damage the bamboo scrim of the cable and affect its electrical performance. Moreover, the variable parameters that affect the quality of the welding specification must be strictly controlled. Otherwise, the weld is easy Produce defects. Some domestic units for the gain
