Hobart Champion 4500 Conditions That Affect Weld Bead Shape, Electrode Movement During Welding

11-8. 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 Large
Angle Too Small	10° - 30°

Drag

ELECTRODE ANGLE

Spatter

Too Short	Normal	Too Long
	ARC LENGTH

Slow	Normal	Fast
	TRAVEL SPEED	S-0061

11-9. 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.
