Types of welding beads
Welding positions
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 b) .
2. Horizontal position: This position
prevents the weld puddle from running
downward while allowing slow and
enough travel speed. For this position,
the torch nozzle should be kept at an
angle of 30 degrees with respect to the
work piece
(fig c) .
Stringer bead Weave bead
• The stringer bead is formed by
travelling with the torch in a straight
line while keeping the wire and nozzle
centered over the weld joint
(fig Z) .
• The weave bead is made by weaving the
wire from side to side while moving with
the torch. It can be used when needed to
weld the metal over a wider space
(fig a) .
