Puddle Welding Definition _best_ ❲REAL | 2026❳
The welder applies the arc to the top sheet, creating a molten "puddle" that penetrates and bonds with the heavier steel framing (like beams or joists) underneath.
A puddle weld, formally known as an , is a specialized welding technique used to join overlapping metal sheets, typically by melting through the top layer to fuse it with the supporting structure below. puddle welding definition
: A typical puddle weld is roughly 3/4 inch (19 mm) in diameter . The welder applies the arc to the top
It is most effective when joining thin-gauge steel (such as roof or floor decking) to thicker structural members. It is most effective when joining thin-gauge steel
Success depends on puddle management . Welders must monitor the size, color, and fluidity of the molten pool to ensure full penetration without burning through the base metal excessively. Common Applications
Performed on thin materials (like metal decking) where the arc itself burns through the top sheet to reach the base metal. No pre-punched hole is required.
