摘要： Disclosed is a friction stir welding technique which avoids occurrence of a dent, in a joining region, extending to a level beneath the joined surfaces. At end portions of the frame members to be joined, at the joining region, thickened parts which project toward the rotary body joining tool are provided. Two adjoining thickened parts, of adjacent members to be joined, can form a trapezoid shape. The rotary body joining tool has a small-diameter tip portion and a larger diameter portion. The rotary body joining tool is inserted in the thickened parts. In a state where the rotary body joining tool has been inserted small-diameter tip end first, to a level where the larger diameter portion of the rotary body joining tool overlaps the thickened part but does not extend below the upper surface of the non-thickened surfaces of the members joined, the rotary body is rotated and moved along the joining region. Even when a gap exists between two thickened parts, a desirable joining can be carried out. After the joining, the remaining parts of the thickened parts can be machined so as to form a smooth surface.

摘要： In a roller seam welding machine, the upper welding roller is led through a welding-force adjustment device with two spring elements. One spring is already effective when the initial deflection of the welding roller occurs. The other spring comes into operation only when a certain deflection (D) is reached. A marked improvement in weld quality can be obtained in this way, particularly at the start of the weld seam.

摘要： A method of fabricating a truss core sandwich panel of the type including first and second face sheets secured on opposite sides of a corrugated sheet. The first face sheet is welded to one side of the corrugated sheet and the second face sheet is positioned in contact with the other side of the corrugated sheet. A conductive mandrel is positioned between the first face sheet and the corrugated sheet, the height of the mandrel being less than the distance between the first face sheet and the corrugated sheet by a predetermined amount. The first and second face sheets are positioned between opposed welding electrodes, with the mandrel being coplanar with the electrodes. A welding force is applied to the first and second face sheets by means of the electrodes, the force being sufficient to deflect the first face sheet into contact with the mandrel and to bring the mandrel into contact with the corrugated sheet to permit electrical continuity between the electrodes. The predetermined amount is such that the deflection of the first face sheet will not exceed the yield point of the material thereof. A current is passed between the first and second electrodes to weld the second face sheet to the corrugated sheet and the welding force is released. The mandrel is moved to a new location and the process is repeated.
