Welding in the overhead position is the final problem to master. Again proceed through the steps of making weld beads,
the making of butt welds and finally the making of fillet welds. For overhead welding, the electrode position, Figure 3.38,
will prove helpful. When weaving is necessary, the pattern in Figure 3.38 may be used. The technique for overhead butt
welds is illustrated in Figure 3.0; this covers single pass welds or the first pass of multilayer welds Subsequent beads may
be deposited as shown in Figure 3.1. For depositing single layer fillets or the first layer of multiple fillets in the over- head
position the technique in Figure 3.2 should be employed. The sequence for depositing beads on a multilayer fillet weld
is provided in Figure 3.3. Note that single beads are recommended and for that reason use the same technique shown in
Figure 3.2. Again the technique for fillet welds may be employed for welding lap joints.
