The article deals with experimental research and numerical simulation of pulse heating of high-current electrical contacts in a wide temperature range – up to the melting point. It has been found out that electrode welding begins when the temperature is much lower than the melting point. Peculiarities of softening and melting processes of the contact area are described.
Keywords: high-current electrical contacts, contact area, melting point, electrode welding, softening process.
