BS EN ISO 636:2017规定了焊接状态下杆和钢丝的分类要求 并在焊后热处理条件下进行非合金细晶粒钨极惰性气体保护焊 最小屈服强度高达500 MPa或最小抗拉强度高达570 MPa的钢材。本文件是一个综合规范，使用基于 所有焊接金属的屈服强度和平均冲击能量为47 J，或使用基于 所有焊缝金属的抗拉强度和平均冲击能为27 J。a） 带有后缀字母“a”的段落和表格仅适用于杆和电线 根据allweld的屈服强度和47 J的平均冲击能量分类为系统 符合本文件要求的金属。b） 带有后缀字母“b”的段落和表格仅适用于杆和电线 根据拉伸强度和27 J的平均冲击能量分类为系统 所有焊接金属均应符合本文件要求。c） 既没有后缀字母“A”也没有后缀字母“B”的段落和表格适用 根据本文件分类的所有杆和电线。交叉引用:ISO 544:2011 Ed 4ISO 15792-1:2000 Ed 1（R10）ISO 14344:2010 Ed 2ISO 80000-1:2009 Ed 1ISO 13916:1996ISO 14175:2008 Ed 2 EN 1668:1997购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS EN 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.This document 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 allweld 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.Cross References:ISO 544:2011 Ed 4ISO 15792-1:2000 Ed 1 (R10)ISO 14344:2010 Ed 2ISO 80000-1:2009 Ed 1ISO 13916:1996ISO 14175:2008 Ed 2 EN 1668:1997All current amendments available at time of purchase are included with the purchase of this document.
