Miller Electric Bobcat 225 manual Conditions That Affect Weld Bead Shape

14-8. 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
	TRAVEL SPEED	S-0061

14-9. 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.

1Stringer 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.
