solid-state welding

- May 30, 2018-

Pressure welding is under pressure conditions, so that the two workpieces in the solid state to achieve inter-atomic bonding, also known as solid-state welding. The commonly used pressure welding process is resistance butt welding. When the current passes through the connection ends of the two workpieces, the temperature rises due to the large resistance. When heated to the plastic state, the connection is integrated under the axial pressure.
