SEAL WELD
A weld used primarily to obtain tightness and to prevent leakage.
SEAM WELDING
Welding a lengthwise seam in sheet metal either by abutting or
overlapping joints.
SELECTIVE BLOCK SEQUENCE
A block sequence in which successive blocks are completed in a
certain order selected to create a predetermined stress pattern.
SERIES WELDING
A resistance welding process in which two or more welds are made
simultaneously by a single welding transformer with the total current
passing through each weld.
SHEET SEPARATION
In spot, seam, and projection welding, the gap surrounding the weld
between faying surfaces, after the joint has been welded.
SHIELDED WELDING
An arc welding process in which protection from the atmosphere is
obtained through use of a flux, decomposition of the electrode
covering, or an inert gas.
SHOULDER
See ROOT FACE.
SHRINKAGE STRESS
See RESIDUAL STRESS.
SINGLE IMPULSE WELDING
The making of spot, projection, and upset welds by a single impulse of
current. When alternating current is used, an impulse may consist of a
fraction of a cycle or a number of cycles.
SIZE OF WELD
a. Groove weld
. The joint penetration (depth of chamfering plus the
root penetration when specified).
b. Equal leg fillet welds
. The leg length of the largest isosceles right
triangle which can be inscribed within the fillet weld cross section.
c. Unequal leg fillet welds
. The leg length of the largest right triangle
which can be inscribed within the fillet weld cross section.
d. Flange weld
. The weld metal thickness measured at the root of the
weld.
SKIP SEQUENCE
See WANDERING SEQUENCE.
SLAG INCLUSION
Non-metallic solid material entrapped in the weld metal or between the
weld metal and the base metal.
