    Abstract: PROBLEM TO BE SOLVED: To provide a spot welding device capable of attaining stable welding quality when a workpiece which is a stack of a thick plate and a thin plate is subjected to spot welding.SOLUTION: A workpiece to be welded 100 is clamped between a combination of a second welding electrode 35 and a receiving unit 13 that abut against a thinner plate 101, and a first welding electrode 25 that abuts against a second thicker plate 103, a pressure is applied to the workpiece by the first welding electrode 25, and a current is passed between the first welding electrode 25 and the second welding electrode 35. Consequently, a satisfactory nugget is formed over from the thinner plate 101 to the second thicker plate 103. Similarly, a workpiece to be welded 100 is clamped between a combination of the first welding electrode 25 and the receiving unit 13 that abut against a thinner plate 101, and the second welding electrode 35 that abuts against a second thicker plate 103, a pressure is applied to the workpiece by the second welding electrode 35. Consequently, a satisfactory nugget is formed over from the thinner plate 101 to the second thicker plate 103, thereby the quality of welding to the workpiece to be welded is improved.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for joining a steel band extremely advantageous in welding quality and productivity when producing a steel band used for a tailored blank method by joining steel bands of different kinds. SOLUTION: When continuously welding the edge parts of a plurality of different kinds of steel bands 1, 2, a plurality of steel bands 1, 2 are passed between a welding roll 5 and a plurality of press rolls 3, 4 slantingly arranged so as to apply width direction force to the steel bands, and consequently applying pressing force to the edge part end face of the steel band, a welding position is detected by a position detector 14, and a laser beam emitting tube 6 is moved following the welding position according to the detected value, thus conducting the laser beam welding.

    Abstract: A method of forming an object includes installing multiple foil drums within a processing chamber of an ultrasonic consolidation system. The multiple foil drums each include different materials than the other foil drums. The multiple foil drums are positioned so that one of the foils is selected to be placed on top of the build platform. The selected foil is welded onto the build platform or onto a previously processed layer. A portion of the welded foil is then cut. The multiple foil drums are retracted away from the build platform. The portion of the welded foil that was just cut is then consolidated to the object. The build platform is incrementally lowered before the process is repeated to form the next layer of the object.
