MIG/MMA WELDER

The horizontal positionis
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.
2.5 Judge a 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)
A. Weld speed is too fast.
B. Weld speed is too slow.
C. Arc is too long.
D. Ideal weld.
