Another supplementary symbol shown in figure
3-51 is the weld-all-around symbol. When this symbol
is placed on a welding symbol, welds are to continue all
around the joint.
Welds that cannot be made in the shop are identified
as field welds. Afield weld symbol is shown in figure
3-51. This symbol is a black flag that points toward the
tail of the welding symbol.
Specifying Additional Information
It is sometimes necessary to specify a certain weld-
ing process, a type of electrode, or some type of refer-
ence necessary to complete a weld. In this case, a note
can be placed in the tail of the reference line. (See
Figure 3-54.Representing multiple welds.
Figure 3-55.Example of welding symbol in use.
fig. 3-53.) If additional information is not needed, then
the tail is omitted.
When you are fabricating a metal part, there are
times when more than one type of weld is needed on the
same joint; for example, a joint may require both a bevel
groove weld and a fillet weld. Two methods of illustrat-
ing these weld symbols are shown in figure 3-54. Note
that in each welding symbol, the bevel groove weld is
to be completed first, followed by the fillet weld.
Applying a Welding Symbol
Figure 3-55 shows an example of how a welding
symbol may appear on a drawing. This figure shows a
