10-9. Electrode 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 work better.

Weave Patterns

Use weave patterns to cover a wide

area in one pass of the electrode.

Do not let weave width exceed

2-1/2 times diameter of electrode.
