Achieving a high-quality puddle weld requires balancing heat and timing. Those little circles of steel aren't spots; they

: Filler metal is deposited into the resulting "hole" until it is filled and the puddle reaches roughly ¾ of an inch in diameter . No—only the top side

Visually, a finished puddle weld looks like a small, circular nugget or "button" on the surface of the metal deck.

The molten metal fills the hole and fuses with the perimeter of the top sheet, creating a solid, circular connection. Key Technical Specifications
