When you finish, the hole is filled flush with weld metal.

When most people picture a weld, they imagine a long, glowing bead tracing a seam between two plates of metal. But in the worlds of auto manufacturing, shipbuilding, and heavy fabrication, there is another, less glamorous but equally critical player: the puddle weld (also known as a plug weld or a rosette weld). puddle weld

Those little circles of steel aren't spots; they are puddles of strength holding your world together. Do you have a horror story of a plug weld that failed, or a trick for getting them perfect every time? Let us know in the comments below! Instead of welding the outside edges of the

If you’ve ever wondered how the floor pans are attached to the frame of your car, or how a sheet metal bracket is secured to a hollow tube, you’ve likely seen a puddle weld. Here is your complete guide to what it is, why it’s used, and how to do it right. A puddle weld is a method of joining two pieces of metal—usually where one piece overlaps the other—by melting through a hole in the top layer to fuse it to the bottom layer.
