Final answer:
The type of weld bead created by transverse oscillation of the electrode is known as a weave bead, which is used to cover larger weld joints with a side-to-side technique.
Step-by-step explanation:
The type of weld bead made by transverse oscillation of the electrode is called a weave bead. Weave beads involve moving the electrode back and forth across the weld joint to deposit metal in a weaving fashion. This technique is used to fill a wider joint or tie in both sides of a joint.
In contrast, a stringer bead is a straight weld without much side-to-side motion, often used for thinner metals or joints that do not require additional filler metal. A butt bead typically refers to a bead used to join two pieces of metal end to end in a butt joint, while a fillet bead is specific to a weld that joins two surfaces at approximately a right angle to each other in what is known as a fillet joint.
Welding as a fabrication process, whether using gas, electricity, laser or traditional forge methods, involves the coalescence of materials, often with the use of heat and filler metal to create a strong and durable bond.
