This specification prescribes the requirements for classification of solid carbon steel electrodes and rods, composite
stranded carbon steel electrodes, and composite metal cored carbon steel electrodes for gas shielded arc welding. Classi-
fication is based on chemical composition of the electrode for solid electrodes and rods, chemical composition of weld
metal for composite stranded and composite metal cored electrodes and the as-welded mechanical properties of the weld
metal for each. Additional requirements are included for manufacture, sizes, lengths, and packaging. A guide is appended
to the specification as a source of information concerning the classification system employed and the intended use of the
electrodes and rods.
This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these
units are not equivalent, each system must be used independently of the other.
