1.1 This specification prescribes requirements for the clasifcation of carbon and low-alloy steel fux cored electrodes for fux cored are welding (FCAW), either with or without shielding gas, and carbon and low-alloy steel metal cored electrodes for gas metal are welding (GMAW). Carbon and lowalloy fux cored electrodes had previously been cassifed solely under AWS A5.20/A5.20M, Specification for Carbon Steel Electrodes for Flux Cored Are Welding, or AWS A5.29/ A5.29M, Specification for Low-Alloy Steel Electrodes for Flucr Cored Are Welding. Carbon and low-alloy steel metal cored electrodes have previously been classified solely under AWS A5.18/A5.18M, Specification for Carbon Steel Electrodes and Rods for Gas Shielded Arc Welding, or AWS A5.28/A5.28M, Specification for Low-Alloy Steel Electrodes and Rods for Gas Shielded Arc Welding. lron is the only element of the undiluted weld metal deposited by the electrodes classified under this specification whose content exeeds 10.5%.
