Sets out requirements for cored electrodes for self-shielded and gas shielded automatic or semi-automatic arc welding. Includes low and intermediate alloy ferritic steel electrodes, along with carbon steel electrodes. Provides a coherent system of classification based on the method of construction, type of core, recommended welding position, shielding gas requirements, and weld metal properties. Specifies the properties and requirements for the manufacture of the electrodes and gives the methods of test. A comprehensive guide to the electrodes and other useful information are given in an appendix.

This Standard specifies requirements for the following cored electrodes (as defined in AS 2812) for self-shielded and gas-shielded automatic and semi-automatic arc welding:(a) Carbon steel electrodes.(b) Low or intermediate alloy ferritic steel electrodes.It does not apply to cored electrodes for submerged-arc, electroslag, or electrogas welding.NOTES:1 Throughout this Standard the word 'electrode' applies to both flux-cored and metal-cored electrodes.2 Additional information concerning electrodes is given in Appendix B.
