Resistance spot welding - how it works? [RW03]
The process of resistance spot welding involves several key steps that contribute to the successful fusion of metal sheets. It begins with the preparation of the metal surfaces to be welded, ensuring that they are clean and free from contaminants that could affect the quality of the weld. Once the surfaces are prepared, the metal sheets are positioned between the welding electrodes, which apply pressure to hold them in place during the welding process.

What is diffusion welding? [DW01]
Diffusion welding, or diffusion bonding, is a kind of solid-state joining method which uses indirect heat energy as energy source. It can make the surface of welding parts produce small plastic deformation under certain temperature and pressure, and realize large area close contact. The metallurgical bonding of the weldments is realized by the mutual diffusion of atoms between the contact surfaces and the interface migration. Diffusion welding is regarded as a high precision joining technique, also referred to as diffusion bonding.

Equipment and Materials Used in Resistance Spot Welding [SPW01]
Resistance spot welding requires specialized equipment and materials to facilitate the precise and efficient joining of metal components. The primary components of a resistance spot welding system include welding electrodes, a power supply, and a control unit. The welding electrodes, typically made of copper alloys, apply pressure to the metal sheets and conduct the electrical current necessary for generating heat at the welding points.
