Which welding technique utilizes a consistent, straight motion?

The technique that utilizes a consistent, straight motion is the stringer bead method. This approach involves keeping the electrode or filler material in a linear path along the joint being welded. The straight motion allows for a controlled and predictable bead formation, which is ideal for achieving strong, uniform welds.

Utilizing a stringer bead can lead to better penetration into the base materials and often produces a narrower weld bead compared to other techniques that involve varied movements. This method is particularly effective in situations where a flat, clean joint is being welded, such as in fillet welds or butt joints in flat positions.

In contrast, the other techniques mentioned involve varied movements that do not follow a linear trajectory. The weave pattern incorporates side-to-side motion, the circle technique involves circular movements, and the zigzag motion creates a pattern that alternates direction as it progresses. These methods can be beneficial for specific applications but are not characterized by a consistent, straight motion like the stringer bead technique.
