Figure 7-37.Fillet welds in the vertical position.
Move the electrode in a triangular weaving motion, as
shown in figure 7-37, view A. A slight pause in the
weave, at the points indicated, improves the sidewall
penetration and provides good fusion at the root of the
When the weld metal overheats, you should quickly
shift the electrode away from the crater without break-
ing the arc, as shown in figure 7-37, view B. This permits
the molten metal to solidify without running downward.
Return the electrode immediately to the crater of the
weld in order to maintain the desired size of the weld.
When more than one pass is necessary to make a tee
weld, you may use either of the weaving motions shown
in figure 7-37, views C and D. A slight pause at the end
of the weave will ensure fusion without undercutting the
edges of the plates.
LAP JOINTS. To make welds on lap joints in the
vertical position, you should move the electrode in a
triangular weaving motion, as shown in figure 7-37,
view E. Use the same procedure, as outlined above for
the tee joint, except direct the electrode more toward the
vertical plate marked G. Hold the arc short, and pause
