Describes requirements for classification of solid wire electrodes, tubular cored electrodes and electrode/flux combinations (all-weld metal deposits) for submerged arc welding of creep resisting and low-alloy elevated-temperature steels.

This International Standard specifies requirements for classification of solid wire electrodes, tubular cored electrodes and electrode/flux combinations (all-weld metal deposits) for submerged arc welding of creep resisting and low-alloy elevated-temperature steels. One electrode can be tested and classified with different fluxes. The solid wire electrode is also classified separately based on its chemical composition. This International Standard is a combined specification providing for classification utilizing a system based upon the chemical composition of the solid wire electrode and all-weld metal deposit, or utilizing a system based upon the tensile strength of the all-weld metal deposit and the chemical composition of the solid wire electrode and all-weld metal deposit obtained with the electrode/flux combination. Clauses, subclauses and tables which carry the suffix letter “A?? are applicable only to solid wire electrodes, tubular cored electrodes and all-weld metal deposits classified in accordance with the system based upon chemical composition. Clauses, subclauses and tables which carry the suffix letter “B?? are applicable only to solid wire electrodes, tubular cored electrodes and all-weld metal deposits classified in accordance with the system based upon the tensile strength of all-weld metal deposits and the chemical composition of solid wire electrodes and all-weld metal deposits. Clauses, subclauses and tables which do not have either the suffix letter “A?? or the suffix letter “B?? are applicable to all solid wire electrodes, tubular cored electrodes and electrode/flux combinations classified under this International Standard.
