Zusammenfassung:The present invention discloses laser pressure welding which is used for joining a first metal component with a second metal component; the first metal component has a first joining section with a first joining surface; the second metal component has a second joining section with a second joining surface; laser beams are projected onto the first and second joining sections of the first and second metal components to heat the first and second joining surfaces to a temperature between their re-crystallization temperature and melting temperature respectively; and the first joining surface of the first metal component is pressed tightly against the second joining surface of the second metal component until the first joining and second joining surfaces are cooled to a temperature below their re-crystallization temperature.
