Frequent question: What is weave bead?

What is string or weave bead in welding?

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.

Should you weave when MIG welding?

The general guidelines for MIG welding are whip when welding thin metal or making the first pass in a joint, circles for a both thicker materials and wider welds. Weave for vertical up and down.

Do you weave stick welding?

For welding vertical up, use a push or forehand technique and tilt the top of the electrode 0 to 15 degrees away from the direction of travel. … Note that on material 1/4 inch and thinner, weaving the electrode is typically not needed because the bead will be wider than necessary.

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.

How wide should a weave bead be?

A rule of thumb is that the maximum weave width should be about three times the electrode core wire diameter. Once deposited, weld beads should preferably exhibit a slightly convex surface contour.
