摘要： The present invention provides an improved method of resistance welding comprising the steps of contacting a metal sheet with an electrode having an initial contact surface area at a force to provide a pressure to the metal sheet; applying a current through the electrode to the metal sheet; measuring dimensional changes of the electrode; correlating dimensional changes in the electrode to changes in the initial contact surface area; and adjusting the force to compensate for the changes in the initial contact surface area of the electrode to maintain pressure to the metal sheet. The force may be adjusted by stepping the force to maintain pressure to the faying surface of the metal sheet to be welded. By maintaining the pressure at the faying surface the life cycle of the electrodes may be increased without forming discrepant welds. The current may also be stepped to further extend electrode life.

摘要： The present invention provides a low temperature joining method that is compatible with multiple materials and results in a bond between joined structures without reducing the mechanical properties of the joined structures base materials. The method of the present invention includes the steps of contacting a first structure to a second structure; and directing particles of a metallic bonding material towards an interface between the first structure and second structure at a velocity to cause the particles of the metallic bonding material form a molecular fusion between the first structure and second structure.
