Normally, a single stringer bead is sat-
isfactory for most narrow groove weld
joints; however, for wide groove weld
joints or bridging across gaps, a weave
bead or multiple stringer beads works
better.
1 Stringer Bead - Steady Movement Along
Seam
2 Weave Bead - Side To Side Movement
Along Seam
3 Weave Patterns
Use weave patterns to cover a wide area in
one pass of the electrode. Do not let weave
width exceed 2-1/2 times diameter of
electrode.
