CONNECTIONS

3.28 CHAPTER THREE

Length of weld is not shown on the symbol in this case, because the connection requires a continu-
ous weld the full length of each angle on both sides of the angle. Care must be taken not to omit
length unless a continuous full-length weld is wanted. “Continuous” should be written on the weld
symbol to indicate length when such a weld is required. In general, a tail note is advisable to specify
welds on the far side, even when the welds are the same size.

For many members, a stitch or intermittent weld is sufficient. It may be shown as

This symbol calls for / 4-in fillet welds on the arrow side. Each weld is to be 2 in long. Spacing of
welds is to be 10 in center to center. If the welds are to be staggered on the arrow and other sides,
they can be shown as

Usually, intermittent welds are started and finished with a weld at least twice as long as the length
of the stitch welds. This information is given in a tail note:

When the welding is to be done in the field rather than in the shop, a triangular flag should be
placed at the intersection of arrow and line:

This is important in ensuring that the weld will be made as required. Often, a tail note is advisable
for specifying field welds.
