c. 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 possible, as good results are easier to achieve
in this position.
The HORIZONTAL POSITION is performed very much the same as the flat weld except
that angle B (see HOLDING THE TORCH) is such that the wire, directed more toward the
metal above the weld joint, is to help prevent the weld puddle from running downward while
still allowing slow enough travel speed. A good starting point for angle B is about 30
degrees DOWN from being perpendicular to the work piece.
In the VERTICAL POSITION, it is easier for many people to pull the torch from top to
bottom. It can be difficult to prevent the puddle from running downward. Pushing the torch
from bottom to top may provide better puddle control and allow slower rates of travel speed
to achieve deeper penetration. When vertical welding, angle B (see HOLDING THE
TORCH) is usually always kept at zero, but angle A will generally range from 45 to 60
degrees to provide better puddle control.
The OVERHEAD POSITION is the most difficult welding position. Angle A (see HOLDING
THE TORCH) should be maintained at 60 degrees. Maintaining this angle will reduce the
chances of molten metal falling into the nozzle. Angle B should be held at zero degrees so
that the wire is aiming directly into the weld joint. If you experience excessive dripping of
the weld puddle, select a lower heat setting. Also, the weave bead tends to work better
than the stringer.
