Abstract
Abstract The disclosure relates to a bonding process and apparatus whereby two metals are brought together under pressure from a pair of dies or a die and anvil, the interface between the metals being made to achieve an intimate bond by an elevation in temperature provided by heat energy conducted via a portion of one or both metals protruding from the forceful contact area, heat being applied slightly before or simultaneously with the application of pressure, and more particularly, the peak pressure of the crimping characteristic curve, and from a source other than the dies.
