For most welding jobs you will pull the torch along the weld joint to take advantage of
the greater weld puddle visibility.
Travel speed is the rate at which the torch is being pushed or pulled along the weld
joint. For a fixed heat setting, the faster the travel speed, the lower the penetration
and the lower and narrower the finished weld bead. Likewise, the slower the travel
speed, the deeper the penetration and the higher and wider the finished weld bead
will be.
4.2 Types of Welding Beads - As you become more familiar with your new welder and
better at laying some simple weld beads, you can begin to try some different weld
bead types.
The STRINGER BEAD is formed by traveling with the torch in a straight line while
keeping the wire and nozzle centered over the weld joint. See following figure.
The WEAVE BEAD is used when you want to deposit metal over a wider space
than would be possible with a stringer bead. It is made by weaving from side to
side while moving with the torch. It is best to hesitate momentarily at each side
before weaving back the other way.
4.3 Welding Positions
The FLAT POSITION is the easiest of the welding positions and is most commonly
used. It is best if you can weld in the flat position, if at all possible, as good results are
easier to achieve.
