ABSTRACT:
A threaded joint assembly is provided comprising a first metallic workpiece having an internally threaded cylindrical opening, and a second metallic workpiece having an externally threaded cylindrical surface which is threadingly engaged with the internally threaded opening of the first workpiece. The interthreaded joint between the first and second workpieces are electromagnetically deformed into a permanent interference fit. In consequence of the magneforming process, individual threads at the joint are slightly flattened and squeezed together tip to root to provide a high axial and radial pre-load in the joint. Preferably at least the portions of the first and second workpieces defining the joint are hollow cylinders, and preferably the threads of the joint are tip relieved.
