日本焊接材料标准与国际标准接轨的动向——低合金耐热钢用焊接材料和埋弧焊接用焊剂

New progress of the convergence on Japanese welding materials standards to international standard:Low alloy heat-resistant welding materials and flux for submerged arc welding

介绍了日本的低合金耐热钢用焊接材料和埋弧焊焊剂新标准与国际标准接轨的情况。耐热钢用焊接材料包括焊条、药芯焊丝、填充丝和实心焊丝,适于焊条电弧焊、MAG焊、MIG焊、TIG焊和埋弧焊等。埋弧焊用焊剂既适于接头焊接也适于堆焊,适用的钢种有低碳钢、高强钢、铬钼钢、低温钢、不锈钢、耐热钢、镍及镍合金等。堆焊方法既适用于丝极堆焊也适用于带极堆焊,堆焊层适用于耐磨堆焊或耐蚀堆焊。

This paper introduces the situation of the convergence on new Japanese standards for welding material of low alloy heat- resistant steel and flux for submerged arc welding（SAW） to international standards（ISO）. Heat-resistant steel welding materials include electrode, flux-cored wire, filler wire and solid wire used for SMAW, MAG welding, MIG welding, TIG welding and SAW. Flux fi^r SAW is applied for welded joints and surfacing in low-carbon steel, high-strength steel, chrome-molybdenum steel, low-temperature steel, stainless steel, heat-risistant steel, nickel and nickel alloy and etc. Surfacing includes wire-surfacing and strip-surfacing, whose cladding layers are used for wear resistance and corrosion resistance.
