This standard specifies requirements for the classification of solid wire electrodes, solid wires and rods for fusion welding of titanium and titanium-alloys. The classification of the solid wires and cut lengths and spools of wire is based on their chemical composition.

For titanium welding consumables, the compositions of the wire electrodes for the gas metal arc welding (GMAW) process are the same as for the gas tungsten arc welding (GTAW) process, the plasma arc welding (PAW) process, the laser beam welding (LBW) process, and other fusion welding processes. Therefore, the use of the word "wires/rods" in this classification refers to both "wire electrodes" and "wires and rods" in this standard.

NOTE: In this standard, the word "titanium" is used for "titanium and titanium-alloys."

The classification of titanium wires/rods is based upon the chemical composition of the wires/rods.
