11-8. Conditions That Affect Weld Bead Shape

Weld bead shape is affected by electrode angle, arc length, travel speed, and
thickness of base metal.

NOTE

S-0061

ELECTRODE ANGLE

ARC LENGTH

TRAVEL SPEED

Slow

Normal

Fast

Drag

Too Short

Normal

Too Long

Spatter

Angle Too Small

Angle Too Large

Correct Angle

11-9. 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.

NOTE

S-0054-A

Stringer Bead – Steady
Movement Along Seam

Weave Bead – Side to Side
Movement Along Seam

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.
