What is weave motion bead?

What is the purpose of the weave bead?

What is the purpose of using a weave bead? Besides allowing a wider bead, weaving is used to control heat in the weld puddle. Besides that, you’ll usually want to pause on each side of the weld to achieve good tie in and prevent undercutting of the edges.

What is weaving motion in welding?

Weaving motion (uniform side-to-side motion) is applied to the electrode which gives better fusion of the weld metal. This weaving motion or process should be repeated on welding beads from left to right, right to left, and top to bottom, and bottom to top—to build up an uniform appearance of the weld metal.

What is the difference between Stringer and weave beads?

FILLER PASS WELDING Weave beads, produced by weaving the torch across the joint, can be used on carbon and low-alloy steel in the rolled or horizontal-fixed position. Stringer beads, laid parallel to the joint, are used for welding stainless steel pipe since there is less tendency toward carbide precipitation.

What are the weave bead motion technique used in stick welding?

Weave bead welding involves making a weaving pattern in order to cover a larger surface area. This motion allows you to make cover welds over stringer beads, otherwise known as multipass welding. This technique is used when you are layering welds among one another (making multiple welds on the same seam).

What is a stringer bead?

Stringer bead – A narrow, straight weld bead that is created by moving the SMAW electrode straight along the weld joint. A quality stringer bead should have good tie-in on both sides of the weld.

What is bead in welding?

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.
