2. For multipass welds, deposit a first pass bead using a slight
weave. We emphasize the importance of moving into the
corner to assure penetration into the corner. Weld additional
layers with a side-to-side weave hesitating at the sides long
enough to melt out any small slag pockets and minimize
undercut. Travel slow enough to maintain the shelf without
spilling weld metal.
3. With this technique, slag spills down the weld. As long as no
metal spills, operation is normal. Once welders are familiar
with the EXX18 techniques, they will quickly learn to make
sound welds of excellent appearance.
Horizontal Groove and Overhead Weld Techniques
Weld with a series of first pass beads using a slight circular
motion in the crater. Do not whip. Use 5/32" or smaller
electrodes and currents in the lower portion of the
electrode's range.
