Provides requirements for the classification of solid and composite low-alloy steel electrodes and fluxes for submerged arc welding. Electrode classification is based on chemical composition of the electrode for solid electrodes and chemical composition of the weld metal for composite electrodes. Flux classification is based on the mechanical properties and deposit composition of weld metal produced with the flux and an electrode (solid or composite) classified in this standard. Other requirements include sizes, marking, manufacturing, and packaging. The form and usability of the flux are also included.
