FIELD: metal processing.
SUBSTANCE: invention relates to a method of pressure welding of metal parts and can be used in machine building. Welded parts are compressed. Welding zone is heated to temperature lower than recrystallisation temperature on one side of contact zone with movement of temperature field through contact zone. Welding is carried out. After welding isothermal holding at temperature higher threshold of recrystallisation is carried out.
EFFECT: heating for isothermic curing is performed on one side of contact zone with displacement of recrystallisation front through contact zone.
