Abstract: The present invention provides dissimilar material solid-phase bonding that efficiently forms a robust bonded portion of metal materials having different compositions and/or structures. The present invention is a solid-phase bonding method in which one member is brought into contact with another member to form an interface to be bonded, and a bonding load is applied, thereby forming newly-generated surfaces of the one member and the other member at the interface to be bonded, wherein the one member and the other member are brought into contact to form the interface to be bonded, the temperature of the interface to be bonded is raised using ohmic heating by running current from the one member to the other member, the one member and the other member are combined while having different electrical resistances, the temperature (T1) of the one member and the temperature (T2) of the other member in the vicinity of the interface to be bonded are set so as to differ from one another, the one member and the other member have approximately the same strength at the temperature (T1) of the one member and the temperature (T2) of the other member, and a bonding load for which a bonding pressure corresponding to said strength is applied is set substantially perpendicular to the interface to be bonded.

Abstract: A welding method for welding an overlapping part of a first member and a second member includes: a first welding step of forming a friction-stirred part at a one-end-side spot being a spot that is closest to one end of the overlapping part by plunging a rotary tool into the one-end-side spot; a second welding step of forming a friction-stirred part at an other-end-side spot that is located away from the one-end-side spot and closer to the other end by plunging the rotary tool into the other-end-side spot; and a third welding step of forming a friction-stirred part at an intermediate spot located between the one-end-side spot and the other-end-side spot by plunging the rotary tool into the intermediate spot.

Abstract: A novel spot welding method for steel sheets and an aluminum alloy sheet, includes stacked sheet materials from a pair of opposing electrodes to join the sheet materials by resistance heating. The pair of opposing electrodes are in pressure contact with both outer surfaces of the sheet sets. The sheet sets include at least a first and second steel sheet, and an aluminum alloy sheet stacked in this order. A first energization step forms a molten pool between facing surfaces of the first and second steel sheets without melting the aluminum alloy sheet. A second energization step causes a melting reaction between facing surfaces of the second steel sheet and the aluminum alloy sheet. The first and second steel sheets are joined via a first nugget. The second steel sheet and the aluminum alloy sheet are joined via a second nugget including an intermetallic compound generated by the melting reaction.

Abstract: A method for solid state joining of dissimilar materials using a friction stir welding device wherein a pin is inserted through an aperture defined in a first material and a second material to hold the materials together and then held in place by friction stir welding a portion of the pin to a material adjacent said pin, or by friction stir welding a cap or plug that holds the pin in place to the adjacent material. The result is a connection or join wherein the central portion of the pin is not friction stir welded but the portions holding the pin in place (the ends or caps) generally are.

Abstract: A method of resistance spot welding a steel workpiece and an aluminum or aluminum alloy (“aluminum”) workpiece together includes several steps. One step involves providing a workpiece stack-up with a steel workpiece and an aluminum workpiece. Another step involves attaching a cover over a weld face of a welding electrode. The cover is made of a metal material with an electrical resistivity that is greater than an electrical resistivity of a material of the welding electrode. Yet another step involves performing multiple individual resistance spot welds to the workpiece stack-up. The cover abuts the aluminum workpiece while the individual resistance spot welds are performed. And another step involves removing the cover from the welding electrode after the individual spot welds are performed.

Abstract: A method of spot welding a workpiece stack-up that includes a steel workpiece and an aluminum alloy workpiece involves passing an electrical current through the workpieces and between welding electrodes that are constructed to affect the current density of the electrical current. The welding electrodes, more specifically, are constructed to render the density of the electrical current greater in the steel workpiece than in the aluminum alloy workpiece. This difference in current densities can be accomplished by passing, at least initially, the electrical current between a weld face of the welding electrode in contact with the steel workpiece and a perimeter region of a weld face of the welding electrode in contact with the aluminum alloy workpiece.

Abstract: A method of resistance spot welding a steel workpiece and an aluminum or aluminum alloy workpiece together includes several steps. In one step a workpiece stack-up is provided. The workpiece stack-up includes a steel workpiece and an aluminum or aluminum alloy workpiece. Another step involves providing a first welding electrode that confronts the aluminum workpiece, and providing a second welding electrode that confronts the steel workpiece. The first welding electrode has an electrode body and an insert that functions to limit or eliminate heat flux into the electrode body. Other steps of the method involve bringing the first and second welding electrodes into contact with opposite sides of the workpiece stack-up and resistance spot welding the stack-up.
