ABSTRACT:
An apparatus and method for joining structural members to form preforms and structural assemblies are provided. The structural members are positioned so that joining surfaces thereof define an angled aperture, such a slot or frustoconical bore, that receives a corresponding joining member. The joining member is urged into the aperture against the joining surfaces and moved, for example, by oscillating or rotating the joining member, to friction weld the joining member to the structural members. Each structural member can include a clamping portion that is received by a clamping device that prevents the aperture from opening as the joining member is urged into the aperture. A gripping portion of the joining member and the clamping portions of the structural members can be trimmed from the resulting preform to form a finished structural assembly.
