2.3 Types of weld bead
The following paragraphs discuss the most commonly used arc welding beads.
The stringer bead is formed by traveling with the electrode in a straight line while
keeping it centered over the weld joint.
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 electrode. It is best to hesitate momentarily at each side before
weaving back the other way to improve penetration.
2.4 Welding position
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.
The horizontal position is performed very much the same as the flat weld except that
the angle is different such that the electrode, and therefore the arc force, is directed
more toward the metal above the weld joint. This more direct angle helps prevent the
weld puddle from running downward while still allowing slow enough travel speed to
achieve good penetration. A good starting point for your electrode angle is about 30
degrees DOWN from being perpendicular to the work piece.
