鞍钢修建部结构车间,在焊接一百六十毫米的厚板中,采用双机头、四根管状焊条、双送丝的方法取得成功。过去采用的管状焊条丝极电渣焊为单机头、单根管状焊条、单送丝的方法,曾焊接了八座高炉、两座一百五十吨转炉、钢水罐等大型冶金设备。但焊接最大板厚仅为七十至一百毫米。采用这 The structural workshop of the Anshan Iron and Steel Construction Department was successfully used in the welding of 160 mm thick plates using double heads, four tubular electrodes and double wire feeding. In the past, tubular electrode wire electroslag welding was used as a single head, a single tubular electrode, and a single wire feeding method. It had welded eight large blast furnaces, two 150-ton converters, steel tanks and other large-scale metallurgical equipment. However, the maximum plate thickness for welding is only 70 to 100 mm. Adopt this
