Solar container projection welding machine process

What is the principle of projection welding?

Principle of projection welding. The method can also be used for welding metal sheet to the ends of bars, rods or pipes, or for welding nuts to sheets. Wire grids (i.e. the crossing points of the wires) are also particularly suitable for projection welding.

What is a projection welder?

As mentioned, this type of welding machine uses weld projections on the component to create multiple high-quality welds in one go, hence the name ‘projection welder’. Welding many welds at once often require a greater weld force and therefore a stronger frame compared to a simple spot weld.

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 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. Stationary Projection Welding Machine (Pneumatic)

What are the different types of projection welding?

We can distinguish two main types when it comes to projection welding: embossed and solid projection welding. Embossed projections are created directly on the source material and they concentrate the current flow on these projections. These are mostly used for sheet-to-sheet welding.

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.
