Method for connecting a hollow profile to a two-dimensionally contacting component
The invention relates to a process for joining a hollow profiled section ( 1 ) to a component ( 2 ) of a vehicle which bears flat against it by means of soldering, with a solder ( 4 ) being introduced between the hollow profiled section ( 1 ) and the component ( 2 ) and then being liquefied by the introduction of energy and, as it solidifies, producing a fixed join between the hollow profiled section ( 1 ) and the component ( 2 ). To achieve a durable soldered join between the hollow profiled section ( 1 ) and a component ( 2 ) of any desired configuration which bears flat against it in a simple way, it is proposed that a hollow ( 3 ) is formed on the component ( 2 ), in that the solder ( 4 ) is deposited in the hollow ( 3 ), in that the component ( 2 ) is then positioned relative to the hollow profiled section ( 1 ) with the hollow opening ( 6 ) facing the hollow profiled section ( 1 ), and in that then, in the contact position, the component ( 2 ) is acted on by resistive electricity in the hollow region, with a compressive force being exerted on the hollow outer side ( 8 ) by means of a resistance-welding electrode.
1 . A process for joining a hollow profiled section to a component of a vehicle which bears flat against it by means of soldering, with a solder being introduced between the hollow profiled section and the component and then being liquefied by the introduction of energy and, as it solidifies, producing a fixed join between the hollow profiled section and the component, comprising
forming a hollow ( 3 ) on the component ( 2 ), depositing the solder ( 4 ) in the hollow ( 3 ),
positioning the component ( 2 ) relative to the hollow profiled section ( 1 ) with the hollow opening ( 6 ) facing the hollow profiled section ( 1 ), and
then, in the contact position, acting on the component ( 2 ) by resistive electricity in the hollow region, with a compressive force being exerted on the hollow outer side ( 8 ) by means of a resistance-welding electrode.
2 . The process as claimed in claim 1 , wherein the hollow ( 3 ) is stamped out of the component ( 2 ).
3 . The process as claimed in claim 1 , wherein two opposite peripheral regions of the hollow ( 3 ) are completely severed, in such a manner that these peripheral regions are spaced apart in the peripheral direction by in each case a peripheral region which is attached to the component ( 2 ).
4 . The process as claimed in claim 1 , wherein to form the hollow, a tab ( 10 ) is cut and pressed out of the component ( 2 ), with the tab ( 10 ) remaining attached to the component ( 2 ) at one end.
5 . The process as claimed in claim 1 , wherein the production of the hollow ( 3 ) and the deposition of the solder ( 4 ) in the hollow ( 3 ) are carried out by means of a common ram in a single working step or in a plurality of successive process steps.
