标准摘要
[中文适用范围]： 本文件规定了根据全焊金属化学成分、芯类型、保护气体、焊接位置和全焊金属力学性能（以热态或热处理状态）对管状焊剂和金属芯电极及焊条进行分类的要求，用于气体保护和非气保护金属电弧 welding of stainless and heat-resisting steels. [外文原描述]： ISO 17633:2017 specifies requirements for classification of tubular flux and metal cored electrodes and rods, based on the all-weld metal chemical composition, the type of core, shielding gas, welding position and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for gas shielded and non-gas shielded metal arc welding of stainless and heat-resisting steels. ISO 17633:2017 is a combined standard providing for classification utilizing a system based upon nominal composition or utilizing a system based upon alloy type. a) Clauses, subclauses, and tables which carry the suffix letter "A" are applicable only to products classified using the system based upon nominal composition. b) Clauses, subclauses, and tables which carry the suffix letter "B" are applicable only to products classified using the system based upon alloy type. c) Clauses, subclauses, and tables which do not have either the suffix letter "A" or the suffix letter "B" are applicable to all products classified in accordance with this document. ISO 17633:2017 does not use pulsed current for determining the product classification.
