Therefore, considering the weld as a line provides a direct method of designing welds
for bending and/or torsion of the weld line. The moment of inertia in the direction par-
allel to and perpendicular to the longitudinal weld axis is required for situations where
welds are subjected to bending and torsion. Example 9.1 illustrates the calculation of
weld line properties for a particular weld configuration.
