2. Vertical Down
The E7014 Stick electrode makes welding in this
position particularly easy. Use a 3.2mm electrode
at 100 amps. The tip of the electrode is held in light
contact with the work and the speed of downward
travel is regulated so that the tip of the electrode
just keeps ahead of the slag. The electrode should
point upwards at an angle of about 45º.
The electrode is held at 45º to the horizontal and
tilted 10º in the line of travel (Figure 1-28). The
tip of the electrode may be touched lightly on the
metal, which helps to give a steady run. A weave
technique is not advisable for overhead fillet welds.
Use a 3.2mm E6013 Stick electrode at 100 amps,
and deposit the first run by simply drawing the elec-
trode along at a steady rate. You will notice that the
weld deposit is rather convex, due to the effect of
gravity before the metal freezes.

Use a short arc, and do not attempt to weave on
the first run. When the first run has been completed
de-slag the weld deposit and begin the second run
at the bottom. This time a slight weaving motion is
necessary to cover the first run and obtain good
fusion at the edges.
At the completion of each side motion, pause for
a moment to allow weld metal to build up at the
edges, otherwise undercut will form and too much
metal will accumulate in the centre of the weld. Fig-
ure 1-26 illustrates multi-run technique and Figure
1-27 shows the effects of pausing at the edge of
weave and of weaving too rapidly.
3. Overhead Welds
Apart from the rather awkward position necessary,
overhead welding is not much more difficult that
down hand welding.
Set up a specimen for overhead welding by first
tacking a length of angle iron at right angles to an-
other piece of angle iron or a length of waste pipe.
Then tack this to the work bench or hold in a vice
so that the specimen is positioned in the overhead
position as shown in the sketch.
