12-8. Conditions That Affect Weld Bead Shape

Weld bead shape is affected by electrode angle, arc length, travel speed, and

thickness of base metal.

12-9. 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

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.

Do not let weave width exceed

2-1/2 times diameter of electrode.
