Final answer:
A weave bead is created by a side-to-side motion of the welding torch, which helps to distribute the heat and filler material evenly over the welded joint.
Step-by-step explanation:
A weave bead is made with a side-to-side motion. This motion refers to the oscillation of the welding torch while creating a weld bead.
A welder moves the torch side to side to evenly distribute the heat and filler material over the joint being welded. This contrasts with a stringer bead, where the motion is steady and straightforward without going side to side.
