Miller Electric 6000 Conditions That Affect Weld Bead Shape, Electrode Movement During Welding

12-8. Conditions That Affect Weld Bead Shape

NOTE

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

	Correct Angle
Angle Too Small	10° - 30°	Angle Too Large

Drag

ELECTRODE ANGLE

Spatter

Too Short	Normal	Too Long
	ARC LENGTH

Slow	Normal	Fast
	TRAVEL SPEED

12-9. Electrode Movement During Welding

NOTE

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
1	2	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.
