A method of making a face mask including the steps of providing a plurality
of lengths of Grade 2, commercially pure titanium wire, having a diameter
of from about 0.21 to about 0.24 inches; forming each length at room
temperature to a desired bend angle by bending the member at room
temperature using rotary bending apparatus to a first bend angle that is
from about 1.25 to about 1.35 times greater than the desired bend angle;
and welding each of the thus formed lengths to at least one other of the
lengths in an ambient, oxygen containing environment.
