An American National Standard. Approved by American National Standards Institute June 8, 2005. Prepared by American Welding Society (AWS). Supersedes ANSI/AWS A5.29:1998. 54p. This specification prescribes requirements for the classification of low-alloy steel electrodes for flux cored arc welding (FCAW) either with or without shielding gas. Iron is the only element whose content exceeds 10.5 percent in undiluted weld metal deposited by these electrodes. Metal cored low-alloy steel electrodes are not classified under this specification but are classified according to AWS A5.28/A5.28M.
