THROAT DEPTH
In a resistance welding machine, the distance from the centerline of the
electrodes or platens to the nearest point of interference for flatwork or
sheets. In a seam welding machine with a universal head, the throat
depth is measured with the machine arranged for transverse welding.
THROAT OF FILLET WELD
a. Theoretical
. The distance from the beginning of the root of the joint
perpendicular to the hypotenuse of the largest right triangle that can be
inscribed within the fillet-weld cross section.
b. Actual
. The distance from the root of the fillet weld to the center of
its face.
TOE CRACK
A crack in the base metal occurring at the toe of the weld.
TOE OF THE WELD
The junction between the face of the weld and the base metal.
TORCH
See CUTTING TORCH or WELDING TORCH.
TORCH BRAZING
A brazing process in which bonding is produced by heating with a gas
flame and by using a nonferrous filler metal having a melting point
above 800 °F (427 °C), but below that of the base metal. The filler
metal is distributed in the joint of capillary attraction.
TRANSVERSE SEAM WELDING
The making of a seam weld in a direction essentially at right angles to
the throat depth of a seam welding machine.
TUNGSTEN ELECTRODE
A non-filler metal electrode used in arc welding or cutting, made
principally of tungsten.
UNDERBEAD CRACK
A crack in the heat affected zone not extending to the surface of the
base metal.
UNDERCUT
A groove melted into the base metal adjacent to the toe or root of a
weld and left unfilled by weld metal.
UNDERCUTTING
An undesirable crater at the edge of the weld caused by poor weaving
technique or excessive welding speed.
UPSET
A localized increase in volume in the region of a weld, resulting from
the application of pressure.
