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.
d. Multiple Pass Welding
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 between the two pieces
of metal that will have to be welded closed. In most cases more than one pass or bead
will need to be laid into the joint to close the “V”.
Laying more than one bead into the same weld joint is known as a multiple-pass weld.
The illustrations in the following figure show the sequence for laying multiple pass
beads into a single “V” butt joint.
