9.3 Types of weld bead
The following paragraphs discuss the most commonly used arc welding beads.
The stringer bead Formed by traveling with the electrode in a straight line while keeping the
electrode centered over the weld joint.
Stringer Bead
Weave Bead
The weave bead 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.
8.4 Welding position
Flat position It 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.
Flat Position
Horizontal Position
The horizontal position it 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.
9.5 Judge the good weld bead
When the trick of establishing and holding an arc has been learned, the next step is learning how to
run a good bead. The first attempts in practice will probably fall short of acceptable weld beads. Too
long of an arc will be held or the travel speed will vary from slow to fast (see following)
