Motions
Manipulation depends on the joint. Some of the common
motions are shown above.
Motion "A" is a straight whipping motion used with fast-
freeze electrodes to make stringer beads in all positions and
on all types of joints. It keeps the molten pool small and lets
it freeze quickly so the weld metal doesn't spill down or
through the joint. Keep arc short when in the crater and
longer during whip out from the crater.
Motion "B" is a whipping motion combined with a slight
weave in the crater. It is used with fast-freeze electrodes as
the first pass on vertical fillets and V-butts.
Motion "C" is a simple side-to-side weave used with all
types of electrodes to make fill passes on vertical fillets and
V-butts. Also sometimes used with fill-freeze and low
hydrogen electrodes to make the first pass on these joints.
Motion "D" is a triangular weave used with fill-freeze and
low hydrogen electrodes to make one pass vertical fillets
and V-butts. It results in a larger weld than Motion "C''.
Motion "E" is a box weave used with all types of elec-
trodes to make fill passes on vertical fillets and V-butts. It
is similar to Motion "C,'' but with a distinct pause and
slight upward motion at each edge of the weld to assure
complete crater filling and elimination of undercut.
Motion "F" is a circular motion used with all types of elec-
trodes to make overhead welds. Sometimes accompanied
by a slight whip after each oscillation in the crater. Always
use a series of stringer beads overhead; do not weave.
Motion "G" is a simple side-to-side weave used with all
electrodes on wide fillets or butts in the flat position.
