Abstract:
In a method for producing a joint between a hollow profile made from steel and a component made from an aluminum material, a positive and material joint is produced by a braze welding process in conjunction with a pressing operation. The hollow profile is first pressed on a seating region of the component. Subsequently, a weld layer with an additive is applied by thermal joining, producing a positive and material joint between the hollow profile and the component. The positive joint is facilitated by first forming an end of the hollow profile to be pressed on. Preferably, forming is done by widening the end to be pressed on into the shape of a collar.
