AS/NZS ISO 18276:2022
Welding consumables — Tubular cored electrodes for gas-shielded and non-gas-shielded metal arc welding of high strength steels — Classification
Standard identically adopts ISO 18276:2017, which specifies the requirements for the 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.
