摘要： Methods and apparatus for producing melt welds between a plurality of metal parts in which a high frequency current is caused to flow between two areas on opposite sides of the desired melt weld for a time sufficient to melt the metal between such areas, the molten metal then being permitted or caused to cool. The frequency of the current is selected in relation to the characteristics, both electrical and mechanical, of the parts to be welded and so as to provide a current magnitude which will not cause expulsion of the molten metal by reason of the motor effect. The current frequency is selected to be at least high enough to provide an effective resistance of the metal which is at least equal to the contact resistance between the parts. The apparatus may include high temperature insulating material for confining the molten metal, proximity conductor means for influencing the current path and/or magnetic means adjacent the current path for concentrating the current.

摘要： Two adjacent re-entrant surfaces of metal parts to be welded together, at least one of the parts having metal extending in a direction away from an edge of its surface, and the metal immediately adjacent to such surfaces are heated to forge welding temperature by an induction coil supplied with an electric current having a magnitude and frequency for a time which will cause such heating without significant melting of the metal or over-heating and consequent damage to the remainder of the parts and after the forge welding temperature is reached, pressure sufficient to forge weld the parts together at such surfaces is applied to the parts.
