Puddle Weld _top_ Jun 2026

: Once the base metal is molten, the welder uses a circular motion with the electrode, moving outward from the center.

A , also known as an arc spot weld , is a critical structural joining technique used primarily to fasten thin-gauge metal—most commonly steel decking—to heavier structural steel frames. Unlike traditional plug welds that require a pre-punched hole, a puddle weld uses high heat to melt through the top sheet directly and fuse it into the supporting member. The Mechanics of Puddle Welding puddle weld

While puddle welds are efficient, they are not without their challenges. Because the welder cannot see the underlying steel beam directly, they must rely on technique and sound. : Once the base metal is molten, the
