The fillet weld symbol may be used in combination with other symbols, Figure 12.18. This is also true of many of the other weld symbols. Figure 12.18(a) shows the application of the fillet weld on the opposite (other) side of a square

groove weld. Figure 12.18(b) shows the application of a FIGURE 1 2.1 8(a, b) ■ Use of the fillet weld

In summary, the fillet weld symbol may include:

a. Arrow side, other side, or both sides indication

jT-r

b. Size of legs

c. Length of weld

d. Extent of weld

e. Increment of welds and pitch
