manufactured by a hydroforming process overlapping connection and method of connecting tubular members

overlapping compound prepared by a hydroforming process (10), comprising: a first manufactured by a hydroforming process tubular member (12) having a recess (18) therein; a second, manufactured by a hydroforming process tubular member (14) having one end (16); wherein the end (16) of the second manufactured by a hydroforming process the tubular element (14) in the recess (18) of the first, manufactured by a hydroforming process tubular member (12) is arranged to the first, by a hydroforming to connect process produced tubular member (12) and the second, manufactured by a hydroforming process tubular member (14) with each other between the first manufactured by a hydroforming process tubular element (12) and the second, by a hydroforming process produced tubular element (14) to form a lap joint; wherein the second, manufactured by a hydroforming process tubular member (14) comprises a plurality of planar surfaces forming the end; and wherein the planar surfaces, a first surface (34) which is substantially horizontal, a ...
