Vertical Up Techniques for Fillet and Groove Welds

Whip first pass

Box weave second pass

Straight weave

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.
