Manual 0-5420 4-13 BASIC WELDING GUIDE
45º from the vertical. Some electrodes require to be sloped
about 20º away from the perpendicular position to prevent
slag from running ahead of the weld. Refer to Figure 4-23.
Do not attempt to build up much larger than 1/4"(6.4mm)
width with a 1/8"(3.2mm) electrode, otherwise the weld
metal tends to sag towards the base, and undercut forms on
the vertical leg. Multi-runs can be made as shown in Figure
4-24. Weaving in HV fillet welds is undesirable.

C. Vertical Welds
1. Vertical Up
Tack weld a three feet length of angle iron to your
work bench in an upright position. Use a 1/8"(3.2mm)
E7014 Stick electrode and set the current at 100
amps. Make yourself comfortable on a seat in front
of the job and strike the arc in the corner of the
fillet. The electrode needs to be about 10º from the
horizontal to enable a good bead to be deposited.
Refer Figure 4-25. 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. Figure 4-26 illustrates multi-run technique
and Figure 4-27 shows the effects of pausing at the
edge of weave and of weaving too rapidly.

2. Vertical Down
The E7014 Stick electrode makes welding in this po-
sition particularly easy. Use a 1/8"(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.
3. Overhead Welds
Apart from the rather awkward position necessary,
overhead welding is not much more difficult that
downhand welding. Set up a specimen for overhead
welding by first tacking a length of angle iron at right
angles to another 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
