Vertical Up Techniques for Fillet and Groove Welds

1. Make first pass root beads with a whipping technique. Whip

the electrode tip out of the molten crater and up for a short
time to let the crater cool before returning the electrode tip to
the crater area to add more weld metal.

2. Root pass beads, particularly when made with a

whipping technique, tend to be humped in the middle.
Therefore, a box weave is often needed for the second pass
to assure good fusion along the edge of the first bead. The
box weave is similar to the straight weave except a slight
upward motion is made at both sides of the weld. Maintain a
short arc with no whipping.

3. Employ a straight weave for the final passes. Simply move

the electrode tip back and forth across the surface of the
weld pausing slightly at both edges to insure penetration and
wash-in without undercut.

Overhead Techniques
Weld overhead as a series of root beads using a slight
circulation motion in the crater sometimes accompanied by a
whip. Weave beads are too fluid and will spill
