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.
