10-7. Conditions That Affect Weld Bead Shape

S-0061

Slow

Normal

Fast

Drag

Too Short

Normal

Too Long

Spatter

Angle Too Small

Angle Too Large

Correct Angle

Electrode Angle

Arc Length

Travel Speed

Weld bead shape is affected
by electrode angle, arc

length, travel speed, and thick-

ness of base metal.

10-8. Electrode Movement During Welding

S-0054-A

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.

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 elec-

trode. Do not let weave width ex-

ceed 2-1/2 times diameter of

electrode.

10-9. Welding Lap Joints

S-0063 / S-0064

Electrode

Single-Layer Fillet Weld

Move electrode in circular motion.
3

Multi-Layer Fillet Weld

Weld a second layer when a heavi-

er fillet is needed. Remove slag be-

fore making another weld pass.

Weld both sides of joint for maxi-

mum strength.

Or Less
