What is one key characteristic of stringer beads?

Stringer beads are known for requiring minimal motion during the welding process. This characteristic makes them distinct from other bead types, as the technique involved is straightforward and involves a steady travel speed with slight oscillation if needed. The efficiency and simplicity of applying stringer beads allow for consistent width and penetration in welds, leading to a cleaner appearance and better control over the weld pool.

In contrast, other bead styles, such as weave or cushion beads, often require more intricate movements or multiple passes to achieve the desired bead shape or penetration. This is not the case with stringer beads, which focus on a direct, linear approach with less complexity. Therefore, the emphasis on minimal motion is what makes stringer beads an effective choice for many welding applications.
