What is Projection Welding? Uses and Working

What is Projection Welding

Are you familiar with projection welding? If you need help, you’re in the right place. Projection welding is a process used in manufacturing and fabrication that uses heat to join two pieces of metal together. This technique has been around since the 1950s and is still widely used today, meaning it must be doing something right! Let’s dive in and learn more about projection welding and how it works.

What is Projection Welding?

Projection welding is a method that uses heat to join two pieces of metal together. It works by applying localized heat to the area where the two metals need to be joined. The spot being welded will usually have a raised bump or “projection” on one side, which helps focus the heat on that specific area.

Projection Welding Working

The process begins with preparing the surface of both metals for welding, then using electrodes to apply pressure as well as current and voltage to create a strong bond between them. This makes sure that the metals are properly aligned before they are heated. After heating, cooling takes place, during which time a strong joint is formed between the two pieces of metal.

Projection Welding Uses

Projection welding is commonly used in manufacturing operations because it creates very strong welds that can hold up under high temperatures and pressures. It’s also particularly useful when joining thin metal sheets or working with materials such as aluminum or magnesium that can easily be damaged by excessive heat or pressure. Additionally, this type of welding offers faster throughput times than other methods, such as riveting or bolting, making it an efficient choice for large-scale production runs where speed is essential.


Projection welding has been around since the 1950s, and it remains one of the most popular forms of metal joining today due to its efficiency, accuracy, strength and durability. Whether you’re looking for a way to produce parts in bulk quickly or joining thinner materials like aluminium or magnesium, projection welding may just be what you need! With its ability to withstand extreme temperatures and pressures, it’s no wonder why so many manufacturers choose this method over others when creating products on an industrial scale.
