Which of the following is true about weave patterns?

Weave patterns involve more complex movements because they require the welder to manipulate the welding torch or electrode in a back-and-forth motion, creating a wider bead than a simple straight stringer bead. This complexity allows for increased control over the weld pool, which can be vital when dealing with joint configurations that need a wider bead to ensure proper penetration and fusion of the base metals. The technique demands more skill and experience from the welder, as precision is necessary to maintain the correct angle and travel speed while achieving the desired weld profile.

In comparison, other options do not hold true in relation to weave patterns. For instance, they are not necessarily faster to execute than stringer beads; in fact, the intricate motion typically makes weave patterns slower. While some may find stringer beads easier to master due to their straightforward technique, weave patterns require a higher level of proficiency. Additionally, weave patterns generally create wider welds rather than narrower ones, which is a crucial aspect of differentiating between the two techniques.
