BS EN ISO 18276:2017规定了管状药芯焊条（带或不带）的分类要求 用于高强度钢在焊态或焊后进行金属电弧焊的气体保护层 最小屈服强度高于550 MPa或最小抗拉强度的热处理条件 强度高于590兆帕。一根管状药芯电极可以用不同的方法进行测试和分类 保护气体，如果与不止一种气体一起使用。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量为27 J。带有后缀字母“A”的子条款和表格仅适用于管状药芯焊条 根据屈服强度和47 J的平均冲击能量分类 本文件中给出的所有焊接金属。带有后缀字母“B”的子条款和表格仅适用于管状药芯焊条 根据拉伸强度和27 J的平均冲击能量分类 本文件中给出的所有焊接金属。没有后缀字母“A”或后缀字母“B”的子条款和表格如下: 适用于根据本文件分类的所有管状药芯焊条。人们认识到，管状药芯电极的工作特性可以通过 使用脉冲电流，但就本文件而言，脉冲电流不用于确定 电极分类。交叉引用:ISO 15792-1:2000 Ed 1（R10）ISO 14175:2008 Ed 2ISO 544:2011 Ed 4ISO 3690:2012 Ed 3ISO 14344:2010 Ed 2ISO 6847:2013 Ed 3ISO 13916:1996ISO 6947:2011 Ed 3ISO 80000-1:2009 Ed 1 EN 12535: 2000购买本文件时可获得的所有当前修订均包含在购买本文件中。

BS EN ISO 18276:2017 specifies the requirements for classification of tubular cored electrodes with or without a gas shield for metal arc welding of high-strength steels in the as-welded condition or in the postweld heat-treated condition with a minimum yield strength higher than 550 MPa or a minimum tensile strength higher than 590 MPa. One tubular cored electrode can be tested and classified with different shielding gases, if used with more than one.This document is a combined specification providing classification utilizing a system based upon the yield strength and an average impact energy of 47 J of the all-weld metal, or utilizing a system based upon the tensile strength and an average impact energy of 27 J of the all-weld metal.Subclauses and tables which carry the suffix letter "A" are applicable only to tubular cored electrodes classified under the system based upon the yield strength and an average impact energy of 47 J of the all-weld metal given in this document.Subclauses and tables which carry the suffix letter "B" are applicable only to tubular cored electrodes classified under the system based upon the tensile strength and an average impact energy of 27 J of the all-weld metal given in this document.Subclauses and tables which do not have either the suffix letter "A" or the suffix letter "B" are applicable to all tubular cored electrodes classified under this document.It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use of pulsed current but, for the purposes of this document, pulsed current is not used for determining the electrode classification.Cross References:ISO 15792-1:2000 Ed 1 (R10)ISO 14175:2008 Ed 2ISO 544:2011 Ed 4ISO 3690:2012 ED3ISO 14344:2010 Ed 2ISO 6847:2013 ED3ISO 13916:1996ISO 6947:2011 Ed 3ISO 80000-1:2009 Ed 1 EN 12535:2000All current amendments available at time of purchase are included with the purchase of this document.
