Welding Projection. 250 mm Weld controller. While it can be also used to join thinner metal pieces together that tends to be a.
In most applications one of the workpiece surfaces features multiple small formed projectionsround dimples elongated ridges or rings or the extended corners of weld nuts. This method is broadly divided into two types. Applications of projection welding.
The most important variables of this assembly technique are the quality of the projections and the response of the cylinder as the projection collapses during the welding time.
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. Projection welds developed via the resistance welding RW process use the design or shape of the part to make discreet individual-point contacts to concentrate the current during welding. Mostly in almost all applications with various small projections are molded on single parts surfaces which need to weld. A very common use of projection welding is the use of special nuts that have projections on the portion of the part to be welded to the assembly.
