标准范围

ISO 18276:2005规定了在焊接状态或焊后热处理状态下，最小屈服强度高于550 MPa或最小抗拉强度高于590 MPa的高强度钢金属电弧焊用带或不带气体保护层的管状药芯焊条的分类要求。如果使用一个以上的保护气体，则可以使用不同的保护气体对一个管状药芯电极进行测试和分类。本文件是一个综合规范，使用基于全焊接金属屈服强度和47 J平均冲击能量的系统，或使用基于全焊接金属抗拉强度和27 J平均冲击能量的系统，提供分类。

ISO 18276:2005 specifies 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 post-weld 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.
