标准范围

ISO 636:2017规定了最小屈服强度高达500 MPa或最小抗拉强度高达570 MPa的非合金钢和细晶粒钢的钨极惰性气体保护焊焊焊态和焊后热处理状态下棒和线的分类要求。ISO 636:2017是一个综合规范，使用基于所有焊缝金属屈服强度和47 J平均冲击能量的系统，或使用基于所有焊缝金属抗拉强度和27 J平均冲击能量的系统，提供分类。a） 带有后缀字母“a”的段落和表格仅适用于根据本文件规定的屈服强度和所有焊接金属47 J的平均冲击能量分类为系统的杆和线。b） 带有后缀字母“b”的段落和表格仅适用于根据抗拉强度和27 J的平均冲击能量分类为系统的杆和钢丝-根据本文件焊接金属。c） 没有后缀字母“A”或后缀字母“B”的段落和表格适用于根据本文件分类的所有棒和电线。

ISO 636:2017 specifies requirements for classification of rods and wires in the as-welded condition and in the post-weld heat-treated condition for tungsten inert gas welding of non-alloy and fine-grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa.ISO 636:2017 is a combined specification providing classification utilizing a system based upon the yield strength and the average impact energy of 47 J of all-weld metal or utilizing a system based upon the tensile strength and the average impact energy of 27 J of all-weld metal.a) Paragraphs and tables which carry the suffix letter "A" are applicable only to rods and wires classified to the system based upon the yield strength and the average impact energy of 47 J of all-weld metal in accordance with this document.b) Paragraphs and tables which carry the suffix letter "B" are applicable only to rods and wires classified to the system based upon the tensile strength and the average impact energy of 27 J of all-weld metal in accordance with this document.c) Paragraphs and tables which have neither the suffix letter "A" nor the suffix letter "B" are applicable to all rods and wires classified in accordance with this document.
