The time that pressure is maintained at the electrodes after the welding
current has stopped.
HORIZONTAL WELD:
A bead or butt welding process with its linear direction horizontal or
inclined at an angle less than 45 degrees to the horizontal, and the parts
welded being vertically or approximately vertically disposed.
HORN:
The electrode holding arm of a resistance spot welding machine.
HORN SPACING:
In a resistance welding machine, the unobstructed work clearance
between horns or platens at right angles to the throat depth. This
distance is measured with the horns parallel and horizontal at the end
of the downstroke.
HOT SHORT:
A condition which occurs when a metal is heated to that point, prior to
melting, where all strength is lost but the shape is still maintained.
HYDROGEN BRAZING:
A method of furnace brazing in a hydrogen atmosphere.
HYDROMATIC WELDING:
See PRESSURE CONTROLLED WELDING.
HYGROSCOPIC:
Readily absorbing and retaining moisture.
IMPACT TEST:
A test in which one or more blows are suddenly applied to a specimen.
The results are usually expressed in terms of energy absorbed or
number of blows of a given intensity required to break the specimen.
IMPREGNATED-TAPE METAL-ARC WELDING
An arc welding process in which fusion is produced by heating with an
electric arc between a metal electrode and the work. Shielding is
obtained from decomposition of impregnated tape wrapped around the
electrode as it is fed to the arc. Pressure is not used, and filler metal is
obtained from the electrode.
INDUCTION BRAZING:
A process in which bonding is produced by the heat obtained from the
resistance of the work to the flow of induced electric current and by
using a nonferrous filler metal having a melting point above 800 °F
(427 °C), but below that of the base metals. The filler metal is
distributed in the joint by capillary attraction.
