Figure 1.1(b)
shows a single fillet weld. This weld is simple
and therefore cheap to apply but could be seriously deficient in
performance.
Figure 1.1(c)
shows a double fillet weld, which takes longer to
apply. Unless access is available to both sides of the joint, it will be
impossible to weld it.
Figure 1.1(d)
illustrates a T-butt/groove weld. This weld normally
requires edge preparation on a horizontal member, and therefore is
more complex and expensive. However, it may be essential for
certain service conditions.
It can be seen from the previous examples that major problems
will arise unless welded joints are carefully specified by the design
office. The situation is particularly critical where, for example, work
is placed with a subcontractor and the instructions need to be espe-
cially precise.
