Welding consumables — Tubular cored electrodes for gas shielded metal arc welding of creep-resisting steels — Classification

General information

30.20     May 8, 2026

ISO

ISO/TC 44/SC 3

International Standard

Scope

ISO 17634:2015 specifies requirements for classification of tubular cored electrodes used in the post-weld heat-treated condition for gas shielded metal arc welding of creep-resisting and low alloy elevated temperature steels. One tubular cored electrode can be tested and classified with different shielding gases. It is a combined specification providing for classification utilizing a system based upon the chemical composition of all-weld metal or utilizing a system based upon the tensile strength and the chemical composition of all-weld metal.
