9-5. Gun Movement During Welding
NOTE
Normally, a single stringer bead is satisfactory 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.

1Stringer Bead − Steady Movement Along Seam
2Weave Bead − Side To Side Movement Along Seam
3Weave Patterns
Use weave patterns to cover a wide area in one pass of the electrode.
