What is a weld formed by a side-to-side motion during welding called?

1. Stringer bead

2. Stagger bead

3. Weave bead

4. Side bead

The correct answer is: Weave bead

A weld formed by a side-to-side motion during welding is referred to as a weave bead. This welding technique involves the welding torch or electrode being moved in a lateral motion while the welder progresses along the joint. The weaving motion allows for a broader heat input, resulting in a wider and flatter weld bead. This technique is particularly useful for wider joints and can improve penetration, helping to fuse the edges more effectively and creating a stronger weld. In contrast, other types of welds do not utilize this side-to-side motion. A stringer bead, for example, refers to a weld that is made in a straight line without any weaving motion, generally providing a narrow bead. A stagger bead and a side bead similarly refer to specific configurations that do not embody the lateral movement characteristic of a weave bead. Understanding the differences between these techniques is essential for selecting the appropriate welding method for a given application.
