How do projection welding machines work?

Projection welding machines apply the current and weld forces on these predetermined weld points, unlike spot welding where the weld is determined by the size or shape of the electrode. These Projections can be produced by embossing on sheet metal, machining or cold forging on a solid piece and press punch on the edge of a piece.

What is the difference between spot welding and projection welding?

Projection welding has a wider range of applications than spot welding; from welding nuts and bolts to sheet components to huge bearings and crossbars that form grating panels. Projection welding machines are usually larger than spot welders and offer more weld power and weld force.

What are the applications of projection welding?

The majority of the time, projection welding is employed in mass production. It has numerous applications: One typical application is nut and bolt welding of hex nuts, square nuts, round nuts, tube nuts, and more. But it is also very common in the production of sheet metal components for automobiles and hot stamping of CD welding.

What are the advantages of using a projection welding machine?

Good examples are welding nuts and bolts on plates or brake drums. There are quite a few advantages to using projection welding machines. Firstly, they require a lower welding pressure and a relatively low current source. And as less current travels through the electrodes, they usually can be used for a longer time.

What is the difference between a solid and a projection welding machine?

Creating multiple projections allows simultaneous welding of multiple weld spots. Solid projection welding on the other hand uses existing projections on the component. Good examples are welding nuts and bolts on plates or brake drums. There are quite a few advantages to using projection welding machines.

What are the components of a projection welding process?

The most crucial components during the projection welding process are the two flat electrodes that are the conductors of heat and electricity. Between the electrodes, the two pieces of metal to be welded together are placed.
