Abstract
There is provided an improved method of manufacturing a rod end joint comprising a rod and one or more ball sections formed at an end or ends of the rod. Said method comprises the steps of rigidly fitting a ball or balls to the end or ends of the rod to form the ball section; and applying external compressive force longitudinally to a neck portion formed with the ball section while the neck portion is subjected to a high frequency annealing so as to plastically deform said rod. A length of the rod before the ball is fitted is greater than a length of the rod of a final product.
