Weave beads are created by moving the torch side to side across the joint in a controlled zigzag pattern. This side-to-side motion distributes heat and filler more evenly, producing a wider, flatter bead that fills the groove better and helps ensure good fusion on both sides while reducing the risk of defects like undercut or porosity. Moving along the weld axis would give a narrower, straight bead, and circular or diagonal motions aren’t the standard approach for a basic weave bead. Focus on a consistent side-to-side sweep with a width that fits the joint, and maintain steady travel speed and current to keep the bead uniform.
