随着工业的发展、技术的进步,现代重型机械的壳体日趋以焊代铸。然而提高生产效果的焊接材料在我国目前仍然是薄弱环节。最近江苏省宜兴丁山特种焊接材料厂在冶金工业部北京建筑研究总院的技术合作下,生产的熔咀管状电渣焊条填补了这项空白,其性能达到了国外同类产品要求。熔咀管状电渣焊条,以φ12×4或φ10×4的无缝钢管为本体,外敷弱酸性造渣剂和铁合金药皮,其长度可按用户需求定尺。在焊接过程中将符合焊接材质要求的φ3.2mm焊丝贯入焊条的管孔中,即可利用交流平特性熔咀电渣焊机对25～70mm的中厚钢板进行自动焊接。
With the development of industry and the advancement of technology, the shell of modern heavy machinery is increasingly being welded and cast. However, improving the production of welding materials in our country is still the weak link. Recently, Yixing, Jiangsu Province, Dingshan Special Welding Materials Plant in the Ministry of Metallurgical Industry Beijing Institute of Building Research under the technical cooperation, the production of melt Tsui tubular slag electrode to fill this gap, its performance has reached the requirements of similar foreign products. Melt Tsui tubular electroslag welding to φ12 × 4 or φ10 × 4 seamless steel pipe as the main body, the external application of weak acid slagging agent and iron alloy coating, the length according to user needs length. In the welding process will meet the requirements of the welding material φ3.2mm wire into the hole in the electrode, you can use the AC flat melting point electroslag welding machine 25 ~ 70mm in the automatic welding plate.
