Projection Welding Is Also Known As. Resistance projection welding also known as projection welding is a widely used method in the vehicle industry for attaching various fasteners to the car body or truck cab see the example from a Scania cab in Fig. It works by contacting copper alloy electrodes to the sheet surfaces whereby.
This process utilizes opposing electrodes to join a header containing the electronic device to a cap designed with a ring or annular projection by running current across the electrodes through both the cap and the header. Projection welding is one kind of resistance weld where the shape or design of the part is used to make subtle point contacts to concentrate the current during welding. Want to thank TFD for its existence.
It is a mechanical device that uses compressed gas to produce a force in a reciprocating linear motion.
Ilektrōd fȯrs metallurgy The force that occurs between electrodes during seam spot and projection welding. Projection welding is one kind of resistance weld where the shape or design of the part is used to make subtle point contacts to concentrate the current during welding. It is manual arc welding process that uses a consumable electrode coated in flux to lay the weld. They also sometimes have projections known as weld nibs or bosses to keep the nut from warping while welding with a high current.
