How should beads be laid when surface welding for buildup work?

When doing surface buildup, the goal is a continuous, fused layer of weld metal. Each bead should merge with the previous weld and the base metal so you end up with a solid, cohesive deposit rather than separate, isolated patches. This complete fusion prevents gaps and porosity and gives uniform thickness and strength to the rebuilt surface. Laying beads as discrete patches with gaps would weaken the buildup, and a zigzag pattern isn’t specifically required for this purpose.
