|This specification prescribes requirements for the classification of
carbon steel electrodes
(solid, composite stranded, and composite metal cored) and rods
(solid) for gas metal arc (GMAW),
gas tungsten arc (GTAW), and plasma arc (PAW) welding.
Safety and health issues and concerns are beyond the scope of this
standard and therefore are not
fully addressed herein. Some safety and health information can be
found in the nonmandatory Annex
Sections A5 and A10. Safety and health information is available from
other sources, including but
not limited to ANSI Z49.1, Safety in Welding, Cutting, and Allied
Processes, and applicable federal
and state regulations.
This specification makes use of both U.S. Customary Units and the
International System of Units
(SI). The measurements are not exact equivalents; therefore, each
system must be used independently
of the other without combining in any way when referring to weld metal
specification with the designation A5.18 uses U.S. Customary Units.
The specification A5.18M uses
SI Units. The latter are shown within brackets  or in appropriate
columns in tables and figures.
Standard dimensions based on either system may be used for sizing of
electrodes or packaging or
both under the A5.18 or A5.18M specifications.
