What is projections welding

Question

Accepted Answer

Projection welding is a type of resistance welding where two or more metal parts are joined together by applying pressure and passing an electric current through the contact points.

Projection welding is commonly used in automotive and appliance manufacturing.
It is suitable for joining parts with projections or embossments.
The projections on the parts concentrate the heat and pressure, ensuring a strong weld.
The process involves placing the parts between two electrodes and applying pressure to hold them together.
An electric current is then passed through the electrodes, creating resistance heating at the contact points.
The heat melts the projections and fuses the parts together.
Projection welding is a fast and efficient method for joining metal parts.
It provides consistent and reliable welds with high strength.
Examples of projection welding applications include joining metal brackets, clips, and electrical contacts.
