The invention relates to a method for producing a connection (1) between a peripherally closed hollow profiled piece (2) and a hollow part (3). The action of a fluidic internal high pressure assists in positively connecting the hollow profiled piece (2) and the part (3) to one another while forming an overlapping connecting area (15). The aim of the invention is to create a connection (1) between the hollow profiled piece (2) and the hollow part (3) which cannot be pulled apart and is rotationally fixed. To this end, the invention provides that surfaces (11) which are undercut by means of the internal high pressure on the walls (12, 13) of the hollow profiled piece (2) and of the part (3) are formed whereby resulting in the formation of at least one common indentation, which produces the positive engagement, on the walls (12, 13) of the hollow profiled piece (2) and of the part (3). In addition, the hollow profiled piece (2), in the connecting area (15), is widened by the internal high pressure into a cross-sectional shape that differs from a circular shape. |
