W48.6-96

1. Scope 1.1 This Standard prescribes requirements for the classification and certification of fluxes and carbon steel electrodes (both solid and composite) for submerged arc welding. 1.2 Welding fluxes and electrodes classified in this Standard are intended for submerged arc welding. This is not intended to preclude their use with any other process for which they are found suitable. 1.3 Fluxes and electrodes covered by this Standard are classified according to the (a) chemical composition of the electrode (for solid electrodes) as specified in Table 1, or the undiluted weld metal produced with a particular flux (for composite electrodes) as specified in Table 2; (b) mechanical properties of the weld metal obtained with a particular flux and a particular classification of solid electrode, or a particular combination of flux and composite wire, as specified in Table 3; and (c) condition of heat treatment in which these properties are obtained. 1.4 This Standard does not allow any solid electrode certified under one classification to be certified under any other classification in this Standard. Any composite electrode certified in combination with a particular flux shall not be certified under any other classification in this Standard except that a composite electrode may be certified under different classifications in combination with different fluxes. Fluxes may be classified under any number of classifications, for weld metal in either or both the as-welded and post-weld heat-treated conditions, or using different electrode classifications. The classification system is illustrated in Figure 1, and explained in Clause A1.2 of Appendix A. 1.5 The values given in SI (metric) units are the standard. The inch/pound (imperial) equivalents in parentheses are for information only. In case of dispute, metric values shall take precedence.
