6.2 Types of weld 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 when torch is traveling in a straight line while keeping the wire and
nozzle centered over the weld joint (See the following figure).
The WEAVE BEAD is used when you want to deposit metal over a wider space which wouldn't be
possible using a stringer bead (without transfer oscillation). It is made by weaving electrode from side
to side with slight hesitation at the end of each oscillation while moving it longitudinally. That is the best
way to improve weld penetration.
6.3 Welding position
Flat position
is 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.
Horizontal position
is performed very much the same way as the flat weld except that the angle B
(see "HOLDING THE TORCH") is such that the wire, directed more towards the metal above the weld
joint is to help prevent the weld puddle from running downwards while still allowing slow enough travel
speed. A good starting point for angle B is about 30 degrees DOWN from being perpendicular to the
workpiece.
