What is the difference between Stringer and weave beads?

What is the purpose of using a 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.

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 work angle?

Work angle is “the relationship between the axis of the electrode to the welders work piece”. Travel angle refers to employing either a push angle (pointing in the direction of travel) or a drag angle, when the electrode is pointed opposite of travel.

What can occur if the current setting is too low?

Setting the amps too low will result in a tall, narrow bead lacking in penetration. The weld will be difficult to start and the arc prone to straying towards one side of a joint in preference to the other.

How much should stringer beads overlap on a filler pass?

Filler passes are made with Stringer beads or weave beads. They should overlap enough so that the finished bead is smooth. Stringer beads usually overlap about 50% and weave beads overlap approximately 25%. Each weld bead must be cleaned before the next bead it started.
