在党八届八中全会的精神鼓舞下,大闹技术革命和技术革新,我們冷焊車間厚板电焊生产小組,试验成一种簡易手工埋弧焊(見附图)。我們是根据躺板极电渣焊和手工半自动埋弧焊的原理。利用直徑10毫米的尢3圓鋼作焊条,AH-348熔剂,仿苏HC-500直流电焊机,反极性焊接,电流是 Encouraged by the spirit of the Eighth Plenary Session of the Eighth Central Committee, the technical revolution and technology innovation were staged. We cold-weld the welding production team of the thick-walled workshop in the workshop and tested it as a simple manual submerged arc welding (see the accompanying drawings). We are based on the principle of electro-slag plate and manual semi-automatic submerged arc welding. The use of special diameter of 10 mm round bar for the welding rod, AH-348 flux, imitation Su HC-500 DC welding machine, reverse polarity welding, the current is
