Abstract: The invention relates to a method for joining a first component (10) to a second component (12), wherein the second component contains a thermoplastic material. The method comprises the following steps: bringing the first component in contact with the second component; heating the thermoplastic material of the second component at least in the vicinity of the first component to a temperature above the softening temperature of the thermoplastic material but below the decomposition temperature of the thermoplastic material; displacing the heated thermoplastic material such that an at least positive connection is created between the first component and the second component; and cooling the thermoplastic material to a temperature below the softening temperature thereof.
