据《经济参考》报道:冶金部建筑研究总院与湖北宜昌市电焊条厂联合研制的交直流两用优质低氢和超低氢系列焊条于1987年12月14日通过部、省鉴定。有关专家认为这种焊条质量已达到国外同类焊条的先进水平,花外汇大量进口这类焊条的历史行将结束。这种焊条是目前用于造船,压力容器、高炉以及高层全钢结构建筑等行业的最佳焊接材料,具有脱渣性、抗裂性、低温冲击韧
According to the “Economic Reference” reported: Metallurgical Building Research Institute of Yichang City, Hubei Province, welding rod plant jointly developed by the AC and DC dual-use high-quality low-hydrogen and ultra-low hydrogen series of electrodes on December 14, 1987 passed the ministry and province identification. Experts believe that the quality of such electrodes has reached the advanced level of similar foreign electrodes, spend a large number of imports of foreign exchange such a history of the wire is coming to an end. The electrode is currently the most suitable welding material for shipbuilding, pressure vessels, blast furnaces and high-rise all-steel construction industries. It has the properties of slag removal, crack resistance, low temperature impact toughness
