Yes, diffusion welding isResistance brazing, common copper connecting wires are welded with it. It is made by stacking dozens or hundreds of copper sheets together and pressing them, and heating them with electricity below the melting point, using the mutual diffusion between atoms to achieve a certain depth of connection.
This brazing method is also called self-brazing or contact reaction brazing. When the heated workpiece can form a series of solid solutions or eutectics, diffusion brazing is achieved.
There are not many welding parameters, there are mainly three, temperature, time and pressure. The temperature is the most important, and the pressure can flatten the small unevenness of the joint surface.
The diffusion welding process has several stages like resistance spot welding: pressure, electric heating, heat preservation, cooling and crystallization
