ABSTRACT:
Simple or complex cross-sectional configuration metal components of an article are bonded together through a forged joint with application of localized high frequency induction heating combined with high energy rate impacting of the metal components together. An improved induction heating and impacting apparatus is provided, including an induction heating element the shape of which varies with substantial variations in the cross-sectional area of each component to provide substantially uniform heating.
