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.
UPSET WELDING:
A resistance welding process in which fusion is produced
simultaneously over the entire area of abutting surfaces, or
progressively along a joint, by the heat obtained from resistance to the
