【英文标准名称】: Low-Alloy Steel Electrodes and Rods for Gas Shielded Arc Welding 【原文标准名称】: 气体保护电弧焊用低合金钢焊条和焊棒 【标准号】: ANSI/AWS A5.28/A 5.28M-2005 【标准状态】: 现行 【国别】: 美国 【发布日期】: 2005 【实施或试行日期】: 【发布单位】: 美国国家标准学会(ANSI)【起草单位】: ANSI【标准类型】: ()【标准水平】: ()【中文主题词】: 低合金钢;电弧焊接;气体保护焊;电焊条;焊接工程【英文主题词】: welding engineering;welding electrodes;arc welding;low-alloy steels;gas-shielded welding【摘要】: This specification prescribes the requirements for classification of solid low-alloy steel electrodes and rods, composite stranded low-alloy steel electrodes, and composite metal cored low-alloy steel electrodes for gas shielded arc welding. Classification is based on chemical composition of the electrode for solid electrodes and rods, chemical composition of weld metal for composite stranded and composite metal cored electrodes and the as-welded or postweld heat treated mechanical properties of the weld metal for each. Additional requirements are included for manufacture, sizes, lengths and packaging. A guide is appended to the specification as a source of information concerning the classification system employed and the intended use of the electrodes and rods. This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these are not equivalent, each system must be used independently of the other.【中国标准分类号】: J33【国际标准分类号】: 25_160_20【页数】: 【正文语种】: 英语
