Sample rotary geometries

Friction welding can accommodate a wide variety of geometries as seen below. The process is best suited to a simple butt joint weld prep. The interface needs to be clean and depending on accuracy/component requirements can either be saw cut square to the axis within 1% or machined. The weld face of both parts needs to be clean and clear of any contaminants, in particular, rust, scale, oxides etc as this can jeopardise weld quality.
