- MIG beads.
- Flux Cored MIG Beads. Conclusion.
What is a weld bead called?
Bead – the deposited filler metal on and in the work surface when the wire or electrode is melted and fused into the steel. A stringer bead is a narrow bead with only a dragging motion or light oscillation, while a weave bead is wider with more oscillation.
What is a stringer bead used for?
Stringer beads, laid parallel to the joint, are used for welding stainless steel pipe since there is less tendency toward carbide precipitation. Stringer beads are recommended for welding all carbon and low alloy pipe in the vertical-fixed position.
Should you weave when MIG welding?
When you weld each pass, treat it like a horizontal weld by weaving or swirling circles through the joint. If you’re running two passes, keep the bead narrower for the first pass.
What is the strongest weld pattern?
The absolute strongest weld that can be made in routine applications would be a type of weld made via the welding technique of Tungsten Inert Gas (TIG) Welding, also known as GTAW welding. TIG welders are known for creating clean and strong welds.
What is the keyhole in welding?
A technique in which a concentrated heat source penetrates partially or completely through a workpiece, forming a hole (keyhole) at the leading edge of the weld pool. As the heat source progresses, the molten metal fills in behind the hole to form the weld bead.
