摘要： The method includes: a first step of forming, at a weld site of laminated layers of a metal foil, using a cutter having a longitudinal cross-sectional shape of a substantially V shape, a notch penetrating the laminated metal foil along a lamination direction and having a linear shape in a plan view, to cause the laminated layers of the metal foil closely contact each other in the lamination direction at an end of the notch; a second step of bringing a welding electrode into pressure contact with the weld site and then energizing the weld site via the welding electrode to perform resistance welding, and a forming step, performed between the first and second steps, of crushing the notch and a raised portion around the notch, to form a recess to thereby compress the notch and the raised portion in the lamination direction.

摘要： The present invention relates to a direct-contact type alternating current (AC) trapezoidal wave aluminum resistance welding process method. AC trapezoidal wave inverter controller capable of controlling a positive and negative half-wave current rising rate, and an AC transformer (no rectifier or silicon-controlled rectifier on a secondary coil of the transformer) with an output voltage of 10-30V, a peak current of 32-70 kiloampere and a frequency of 25-80 Hz are included. The inverter controller and the AC transformer are connected by means of a conductor, a welding electrode, a pressurization mechanism and a cooling system to form resistance welding equipment to enable the equipment to output positive and negative alternating trapezoidal wave current on two sides of the electrode when a workpiece is pressurized and welded and to perform welding according to a specified duty ratio, welding current, frequencies, welding cycle number and welding pressure. Practice proves that the method has the advantages that 50-150 welding spots can be welded while grinding the electrode once each time, service life of the electrode is prolonged by 2-5 times, production efficiency and welding quality are greatly improved, and production cost is reduced, thereby realizing a qualitative leap in aluminum and aluminum alloy resistance welding processes.

摘要： Aluminum-base alloy workpieces have surfaces with films of aluminum oxide which inhibit good contact with weld faces of resistance spot weld electrodes and the faying surfaces of, for example, sheet workpieces stacked for welding. Sometimes, the surfaces of the sheets also are coated with an adhesive or a sealer which further complicates welding. But in accordance with this invention, weld faces of opposing, round, copper welding electrodes are pressed against opposite outside surfaces of the sheets at a spot weld site and weld current is applied to the electrodes in accordance with a three-stage weld schedule to better form each weld. The weld schedule comprises a Conditioning stage (stage 1), a weld nugget Shaping stage (stage 2), and a weld nugget Sizing stage (stage 3).

摘要： A method for producing a metal container includes providing first and second metals. The first metal has a first melting point, and the second metal has a second melting point higher than the first melting point. The first metal is adapted to form an engagement portion. The second metal is in the form of a container having a bottom plate. The first metal has first and second faces. The bottom plate has an outer face. The method further includes positioning the first metal on the bottom plate and heating the first and second metals until the first metal turns into a semi-molten state. The method further includes rotating and compressing a mold onto the first face in order to distribute the semi-molten first metal along the outer face to form the engagement portion. The method further includes removing the mold and engaging a heating member with the engagement portion.

摘要： Weld faces of electrodes for resistance spot welding are formed with a suitable area of protrusions and/or intrusions. The size, shape, and elevation or depths of the protrusions or intrusions are determined for the formation of suitable spot welds in and between metal workpieces such as aluminum or steel panels for vehicle bodies. The protrusions or intrusions are also conceived and used to form an image on at least a visible surface of the welded article to produce an attractive appearance on the surface of the welded sheet.

摘要： A workpiece structure having a hole therein is repaired by preparing a stack having a first confinement sheet, a first donor sheet, a workpiece structure having a hole therein, a plug of a plug material in the hole, optionally a second donor sheet, and a second confinement sheet. The first confinement sheet, the first donor sheet, the second donor sheet, and the second confinement sheet each overlie the hole. The first confinement sheet and the second confinement sheet each melt at a temperature greater than do the first donor sheet, the plug, and the second donor sheet. The stack is locally heated at the hole using an electrical current source to a temperature sufficiently high to locally melt the first donor sheet, the plug, the second donor sheet, and the workpiece structure. The stack is thereafter cooled to solidify all melted material and form a weldment.
