MIG/STICK WELDER

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
.
VERTICAL POSITION 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.
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.

Butt Weld Joints
When butt welding thicker materials you will need to prepare
the edges of the material to be joined by grinding a bevel on the edge of one or
both pieces of the metal being joined. When this is done, a “
V”
is created
