Weld bead shape is affected
by electrode angle,
length, travel speed, and thick-
ness of base metal.

.
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.
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 elec-
trode. Do not let weave width ex-
ceed 2-1/2 times diameter of
electrode.
