Abstract
A method of joining metal workpieces together. The method includes an intermediate metal workpiece between first and second metal workpieces to define gaps therebetween, and positioning induction coils in the gaps. The induction coils are energized, to heat hot portions in the first and second workpieces and intermediate hot portions in the intermediate workpiece in a non-oxidizing atmosphere to at least a hot working temperature. The induction coils are removed from the gaps, and the intermediate workpiece is rotated about an axis thereof. Contact surfaces on the first and second workpieces are pressed against the intermediate contact surfaces of the intermediate workpiece respectively while the intermediate workpiece is rotating, for plastic deformation of at least part of the metal in the hot portions and in the hot intermediate portions. The first, second, and intermediate workpieces are cooled to bond the first and second metal workpieces and the intermediate workpiece together.
