    Abstract: A system for bringing the joint edges of first and second sheet metal components into butting relationship. The components are clamped in opposing clamping assemblies with one of the assemblies being movable toward and away from the other. A fluid motor is mounted on one clamping assembly and a piston extending therefrom is connected to the other clamping assembly through a pair of expandable bladders. By sequentially introducing high and low pressure air to first one bladder and then the other, the movable clamping assembly is caused to move one component toward the other while accommodating any initial misalignment between the edges.

    Abstract: A working tool and a cladding device are interchangeably mounted on a working head of a working apparatus. First, in a condition in which the working tool is attached to the working head, a die blank is subjected to profiling, and also a predetermined portion is cut to thereby form a beveled portion Then, the working tool on the working head is changed to a cladding device to thereby perform cladding on the beveled portion with a required material. Thereafter, the cladding device on the working head is changed again to the working tool to thereby finish the clad portion into a predetermined shape.

    Abstract: A method and apparatus for continuously spot-welding galvanized steel sheets overlapped to be bonded by way of a spot welding machine having a pair of electrodes. The galvanized steel sheets clamp a resistance increasing material including a spacer to ensure a gap between the sheets. Bonding surfaces of the galvanized steel sheets partly contact each other when the pair of electrodes pressurize the galvanized steel sheets such that a part of the gap is retained around the spacer between the bonding surfaces. The retained gap has a size in which zinc melted or vapored when a weld current flows between the electrodes can escape through a weld section of the galvanized steel sheets to outside. The method comprises the step of recording an inter-electrode resistance for each spot when the continuous spot welding is executed by the pair of electrodes. The method estimates an electrode lifetime defined by one of the number of spots and a duration of the spot welding until a sufficient nugget will not be formed by way of the electrodes according to the record of the inter-electrode resistance. The method automatically changes weld conditions to enable the continuous spot welding when the electrode lifetime reaches a predetermined electrode lifetime.

    Abstract: Mash seam welding process and apparatus, wherein two plate-like workpieces having different thickness values are fed and guided by a guiding device such that a length W.sub.H of contact of the thick plate-like workpiece with one of two roller electrodes is smaller than a length W.sub.M of contact of the thin plate-like workpiece with the other roller electrode. In this arrangement, the amount of mashing of the thick plate-like workpiece by the roller electrode is made larger than that of the thin plate-like workpiece by the other roller electrode, so that an interface of the two plate-like workpieces is positioned intermediate between the pair of roller electrodes, whereby a weld nugget formed intermediate between the roller electrodes extends across the interface, permitting the weld to have a sufficient strength owing to a nugget ratio, which is a ratio of a width dimension W.sub.N of the weld nugget in the direction of the interface to a width dimension W.sub.G of the interface.

    Abstract: Capitalizing on the unique feature of our induction heating workcell that permits rapid and controlled heating and cooling of a workpiece within a wide temperature range permits combining several manufacturing operations into a single heating cycle to save time, energy, capital, touch labor, and factory space. For example, we can combine superplastic forming (SPF) with brazing, two operations that occur at temperatures that differ by about 150-200.degree. F. (85-105-C.) or more, to produce quality parts. Or, we can combine SPF with .beta.-annealing; of titanium. Finally, we can combine forming, brazing, and annealing into an economical single cycle. Illustrating our combined cycles, we produce multisheet SPF parts with braze joints at selected locations with improved energy efficiency and at lower cost by heating the multisheet pack to its superplastic forming range below the melting point of the braze alloy, superplastically forming the pack to define braze joints having unmelted braze alloy; increasing the temperature to the braze temperature of the braze alloy, and cooling the pack below the superplastic range to freeze the braze alloy in the braze joint.

    Abstract: The laser beam melts a plate or strip workpiece with the formation of a vapor capillary at a cutting point and the melt is driven off by a cutting gas consisting of a mixture of inert gas and hydrogen gas, the hydrogen gas making up to 25% by volume of the cutting gas. In order to maintain the vapor capillary, the cutting gas is taken to the surface of the melt at the cutting point at such a pressure and with such a pressure distribution that the temperature at the surface of the melt is kept at boiling point and the melt is continuously driven out of the cutting seam in the side away from the cutting direction of the vapor capillary. The plate or strip workpiece can be a magnetic steel sheet. An additional stream of gas, liquid, or solid particles can be used to move melt out of the cutting seam.
