Abstract:
In a method of making a tubular structural part for a motor vehicle, a metal plate is contoured and preformed in at least one shaping step into a tubular body. Subsequently, the tubular body is end-formed into the structural part by internal high-pressure application while free contact regions snugly bear upon one another. The structural part is at least partially heated and quenched in a holding tool acted upon with a coolant.
