"Puddle Welding: A Review of the Process and Its Applications"

Proper geometry is critical. While specific codes vary (e.g., AWS D1.1 for structural steel, AWS D8.8 for automotive), general rules include: puddle welds

, technically known as arc spot welds , are specialized structural connections used primarily to attach thin sheet metal, such as steel decking, to thicker supporting structural members like beams, trusses, or open web joists. Unlike traditional welds that join two edges, a puddle weld is formed by melting through the top sheet to create a "puddle" of molten metal that fuses directly into the supporting steel below.
