摘要: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、MIC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。

Abstract : 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, MAC welding, MIG welding, TIG welding and SAW. Flux for SAW is applied for welded joints and surfacing in low-carbon steel, high-strength steel, chrome-molybdenum steel,low-temperature steel, stainless steel, heat-resistant 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.
Key words: standard; heat-resistant steel; welding materials; submerged arc welding; flux

    低合金耐热钢广泛用于火力发电的锅炉、石油精炼设备、煤液化和煤气化用的反应容器中,这类钢在ISO标准中称为“抗蠕变钢”,在日本则按其成分命名为“钼钢及铬钼钢”这发焊接材料有焊条、药芯焊丝、气体保护焊用填充丝和实心焊丝等。关于埋弧焊接用焊剂,以前对应不同钢种有不同的焊剂标准,如“低碳钢及低合金钢用埋弧焊焊剂”( JIS Z 3352),“不锈钢埋弧焊接用实心焊丝和焊剂”( JIS Z 3324),还有不锈钢带极堆焊用的焊剂等,这次制定的标准则把各钢种,如低碳钢、高强钢、低温钢、耐候钢、耐热钢、不锈钢及带极堆焊用的焊剂都合并在一个标准之中,定名为“埋弧焊用焊剂”。
