This specification provides requirements for the classification
of solid and composite carbon steel and 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. Fluxes may be
classified using a multiple pass classification system or a two-run classification
system, or both, under this specification. Multiple pass classification
is based on the mechanical properties and the deposit composition of weld
metal produced with the flux and an electrode classified herein. Two-run
classification is based upon mechanical properties only. Additional requirements
are included for sizes, marking, manufacturing, and packaging. The form
and usability of the flux are also included. A guide is appended to the
specification as a source of information concerning the classification
system employed and the intended use of submerged arc fluxes and electrodes.
This specification makes use of both U.S. Customary Units and the International
System of Units (SI). Since these are not equivalent, each system must
be used independently of the other.
