Welding position:
4. Overhead position: This is the most
difficult welding position. For this
position, angle A should be maintained
at 60 degrees. Maintaining this angle
will reduce molten metal falling into
the nozzle (fig. P).
Angle B should be zero degrees so that
the wire is aiming directly into the weld
joint. If excessive dripping of the weld
puddle occurs, select a lower heat setting.
Multiple pass welding:
• Butt weld joint: When butt welding
thicker materials, prepare the edges of
the material to be joined by grinding a
bevel on the edges of the metal pieces
being joined. When it is done, a "V" is
created between the two metal pieces.
In most cases, more than one pass or
bead will need to be laid into the joint to
close the "V" (fig. Q).
Note: When using self-shielding flux-core wire,
it is necessary to thoroughly chip and brush the
slag off each completed weld bead before
making another pass.
• Fillet weld joint: Most fillet weld joints on
metals of moderate to heavy thickness
will require multiple passes to produce
a strong joint. The sequence of lying
multiple pass beads into a T-joint
and a lap fillet joint is shown (fig. R).
1. Flat position: This position is easiest and
most commonly used. It is best to weld
in the flat position to achieve good
results (fig. M).
2. Horizontal position: This position
prevents the weld puddle from running
downward while allowing slow and
enough travel speed. For this position,
angle B should be about 30 degrees
downward from being perpendicular to
the workpiece (fig. N).
3. Vertical position: The torch can be easily
pulled from top to bottom in this
position, though it is difficult to prevent
the puddle from running downward.
Pushing the torch from bottom to top
provides better puddle control and
allows slower rates of travel speed to
achieve deeper penetration. For this
position, angle B should be zero and
angle A will vary from 45 to 60 degrees
to provide better puddle control (fig. O).
