Welding consumables. Tubular cored electrodes for gas-shielded and non-gas-shielded metal arc welding of high strength steels. Classification1 Scope This document 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 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
