[Superseded]Welding consumables — Tubular cored electrodes for gas shielded and non-gas shielded metal arc welding of high strength steels — Classification (ISO 18276:2005, MOD)
Specifies a classification system for 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.
