The making of a weld with electrical energy accumulated
electrostatically, electromagnetically, or electrochemically at a
relatively low rate and made available at the required welding rate.
STRAIGHT POLARITY:
The arrangement of direct current arc welding leads in which the work
is the positive pole and the electrode is the negative pole of the
welding arc.
STRESS RELIEVING:
A process of reducing internal residual stresses in a metal object by
heating to a suitable temperature and holding for a proper time at that
temperature. This treatment may he applied to relieve stresses induced
by casting, quenching, normalizing, machining, cold working, or
welding.
STRING BEAD WELDING:
A method of metal arc welding on pieces 3/4 in. (19 mm) thick or
heavier in which the weld metal is deposited in layers composed of
strings of beads applied directly to the face of the bevel.
STUD WELDING:
An arc welding process in which fusion is produced by heating with an
electric arc drawn between a metal stud, or similar part, and the other
workpiece, until the surfaces to be joined are properly heated. They are
brought together under pressure.
SUBMERGED ARC WELDING:
An arc welding process in which fusion is produced by heating with an
electric arc or arcs between a bare metal electrode or electrodes and the
work. The welding is shield by a blanket of granular, fusible material
on the work. Pressure is not used. Filler metal is obtained from the
electrode, and sometimes from a supplementary welding rod.
SURFACING:
The deposition of filler metal on a metal surface to obtain desired
properties or dimensions.
TACK WELD:
A weld made to hold parts of a weldment in proper alignment until the
final welds are made.
TEE JOINT:
A joint between two members located approximately at right angles to
each other in the form of a T.
TEMPER COLORS:
The colors which appear on the surface of steel heated at low
temperature in an oxidizing atmosphere.
TEMPER TIME:
