Projection Welding Process Video

Projection Welding Process Video. Projection welding is a variation of the spot welding process in which raised projections on one or both sheets localize and concentrate the welding energy. Furthermore as current is passed through the system the heated and softened projections collapse and form welds.

Projection welding is a type of resistance welding that focuses current and force to a single point or line at the beginning of a weld. Click on the video below for an overview of projection welding flanged nuts and studs to press hardened AlSi coated steels using capacitor discharge resistance welding. Projection welding is a resistance welding process for joining metal components or sheets with embossments by directly applying opposing forces with electrodes specially.

This technique allows for closer weld spacings on thicker materials than are possible with the conventional approach.

One of the main differences between conventional sheet-to-sheet resistance welding and projection welding is that projection welding is a dynamic process involving considerable movement of the upper electrode. Projection welding is a variation of the spot welding process in which raised projections on one or both sheets localize and concentrate the welding energy. Powered by a vision to blend power saving with aesthetics Artech has today germinated into a force to reckon with in the field of resistance welding. And that would be the projection weld as well.
