8-5. Gun Movement During Welding
.
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.
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.
