Final answer:
A stringer bead is a type of weld bead made without any significant weaving motion; it involves a straight, steady motion of the welding electrode and is often used for thinner materials or in challenging welding positions.
Step-by-step explanation:
The type of weld bead made without any significant weaving motion is known as a stringer bead. Stringer beads are used in various welding processes, and it's a technique where the weld is made with a straight, steady motion without oscillating the electrode back and forth.
This technique is contrary to a weave bead, where the electrode is maneuvered in a weaving motion to create a wider bead. Stringer beads are often used for thinner materials or when precise, controlled welds are necessary. They are also typically used in positions that are difficult to weave, such as overhead welding.
