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.

NOTE

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.
