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.
Do not let weave width exceed
2-1/2 times diameter of electrode.
.
A single stringer bead is
satisfactory for most narrow
groove weld joints. For wide
groove weld joints or bridging
across gaps, a weave bead
works better.

Square Groove Weld
Good for materials up to 3/16 in (5
mm) thick.

Single V-Groove Weld
Good for materials 3/16 through 3/4
in (5-19 mm) thick. Cut bevel with
oxyacetylene or plasma cutting
equipment. Remove scale from
material after cutting. A grinder can
also be used to prepare bevels.
Create 30 degree angle of bevel on
materials in V-groove welding.
