6-5. 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.

2Weave Bead − Side To Side Movement Along Seam

3Weave Patterns

Use weave patterns to cover a wide area in one pass of the electrode.
