Astana energy storage projection welding machine

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 a solid projection welding machine?

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. Firstly, they require a lower welding pressure and a relatively low current source.

What makes a good projection welding setup?

Every projection welding setup needs three main elements: Electrodes make or break the welding process. They must: Water-cooled copper alloy electrodes often work best. Their design varies based on the parts being welded and production speed requirements. Proper part prep leads to better welds. This includes:

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.

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.

How do you calculate the strength of a projection weld?

Strength of a projection weld can be calculated to a simple approximation by area of the dimple and assuming base metal properties for shear/tensile strength, based on type of loading during testing.
