Patent ID: 8168285

Claim:
A first component, for connecting with a second component into a unit for establishing a continuous material, non-disengageable connection by means of compression welding, comprising: a center axis; first and second surfaces forming respective outer edges of the first component; and, a third surface, connecting the first and second surfaces, arranged to be joined to a fourth surface for the second component, and including: in a cross section of the first component passing through the center axis, first and second protrusions formed by first and second sides of a welding hump converging at a distal end, the distal end forming a portion of the first component extending furthest in a first direction parallel to the center axis; a recess with a planar surface connected to the respective first sides of the first and second protrusions of the welding hump and extending in a second direction, perpendicular the first direction, the center axis passing through the planar surface; and, a bead chamber: extending in the second direction, between the first surface and the second side for the first welding hump; at least partially formed by a third side extending toward the first surface; and for receiving weld bead material.
