ABSTRACT:
A method of friction welding wherein the parts to be welded, of materials with inherent Young's moduli, are jigged coaxially, set to rotate with respect to each other under an axial pressure recurrently varying with a frequency which is in inverse proportion to the lower value of the Young's moduli and to the diameter--or to the smaller diameter--of the parts while these are being heated up for welding, whereby, the value of the frequency varies over a range between + and -15% and the parts are then upset-forged together.
