Peripheral welds (weld all round)
Figure 8.12(a)
shows an end plate welded to a rolled steel joist, the
symbol indicting a continuous weld round the end of the joist.
Figure 8.12(b)
shows the symbol indicating a weld all round a
patch plate.
In cases where a continuous weld is required, which involves an
abrupt change in direction, for example, round an internal or exter-
nal corner, the weld all round symbol may be confusing because the
extent of welding may not be obvious. This is shown in
Fig. 8.12(c)
where a stiffened beam contains a cope hole at the inside corner of
the stiffener. The weld all round symbol would not provide as clear
an instruction as the symbol for a double fillet weld in the flat, ver-
tical and overhead welding positions. The multiple arrow system is
quite clear and it would be permissible to omit the dashed line in
the ISO example.
