Method for thermally joining two components made from materials having different heat expansion coefficients comprises cooling one component in a region connected to the joining zone

摘要

Method for thermally joining two components (2, 3) made from materials having different heat expansion coefficients comprises cooling one component (2) made from a material with the higher heat expansion coefficient in a region (8) connected to the joining zone (4). An independent claim is also included for a device for thermally joining two components made from materials having different heat expansion coefficients comprising a unit for heating the two components in a joining zone and a unit for introducing an additive (7) into the joining zone.
