13-8. Conditions That Affect Weld Bead Shape

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

 

Correct Angle

Angle Too Large

Angle Too Small

10° - 30°

 

Drag

 

 

ELECTRODE ANGLE

 

 

 

Spatter

Too Short

Normal

Too Long

 

ARC LENGTH

 

Slow

Normal

Fast

13-9. 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.

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.
