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.
