The length of weld throughout which the correctly proportioned cross
section exits.
ELECTRODE:
a. Metal-Arc
. Filler metal in the form of a wire or rod, whether bare or
covered, through which current is conducted between the electrode
holder and the arc.
b. Carbon-Arc
. A carbon or graphite rod through which current is
conducted between the electrode holder and the arc.
c.Atomic
. One of the two tungsten rods between the points of which
the arc is maintained.
d. Electrolytic Oxygen-Hydrogen Generation
. The conductors by
which current enters and leaves the water, which is decomposed by the
passage of the current.
e. Resistance Welding
. The part or parts of a resistance welding
machine through which the welding current and the pressure are
applied directly to the work.
ELECTRODE FORCE:
a. Dynamic
. In spot, seam, and projection welding, the force (pounds)
between the electrodes during the actual welding cycle.
b. Theoretical
. In spot, seam, and projection welding, the force,
neglecting friction and inertia, available at the electrodes of a
resistance welding machine by virtue of the initial force application
and the theoretical mechanical advantage of the system.
c. Static
. In spot, seam, and projection welding, the force between the
electrodes under welding conditions, but with no current flowing and
no movement in the welding machine.
ELECTRODE HOLDER:
A device used for mechanically holding the electrode and conduct- ing
current to it.
ELECTRODE SKID:
The sliding of an electrode along the surface of the work during spot,
seam, or projection welding.
EMBOSSMENT:
A rise or protrusion from the surface of a metal.
ETCHING:
A process of preparing metallic specimens and welds for macrographic
or micrographic examination.
FACE REINFORCEMENT:
Reinforcement of weld at the side of the joint from which welding was
done.
FACE OF WELD:
