A method of continuously forming a dual seam welded tubular product includes the steps of providing two coils of sheet metal material, uncoiling the two coils and forming the material into opposing sections, bringing the two opposing sections together at a convergence angle of less than about 4°; and welding the two seams created between the two opposing sections. An apparatus is configured to bring the sections together at a convergence angle less than about 4° to produce the tubular product. The tubular product may have a diameter greater than 26 inches.

A nitrogen gas tank, a rotary pump and a mechanical booster pump are connected to a bonding vessel that constitutes a bonding apparatus for carrying out diffusion bonding, the apparatus further comprising a pressure sensor. A nitrogen gas atmosphere is formed inside the bonding vessel, and under control operations of a control circuit, a nitrogen introduction rate is controlled so that a pressure is substantially fixed at a predetermined pressure between 3-105 Pa. At such a state, under the action of a rod of a hydraulic cylinder, a second electrode is brought into proximity with a first electrode, so that ultimately, a first object to be bonded and a second object to be bonded on the first electrode are pressed. Further, current is applied through the first electrode and the second electrode with respect to the first object to be bonded and the second object to be bonded.
摘要:
A substantial portion of the peripheral edges of two panels forming a component of a motor-vehicle body, in particular a front bonnet of a motor-vehicle, is joined by interposing a thermosetting adhesive. Polymerization of the adhesive is obtained by heating, without introducing the structure into an oven, by means of one or more induction heating coil, which are shaped and arranged in proximity and along the peripheral edges of the two panels. The quality of the induction heating process is controlled according to signals output by a thermographic detection camera which is positioned adjustable at a point from which it can acquire a thermographic image of the entire extension of said peripheral edges of the panels to be joined, so as to allow simultaneously controlling the temperature reached by each portion of the peripheral edges of the panels.

A method for producing an electronic device is disclosed. One embodiment provides two soldering partners to be connected to one another at an envisaged joining location and at least one of which includes an electronic component or is formed as such a component, a soldering apparatus having an inductor, and an intermediate plate The soldering partners, the inductor and the intermediate plate are positioned in such a way that the intermediate plate is arranged between the electronic component and the envisaged joining location, on the one hand, and the inductor. The soldering partners are connected at the envisaged joining location by using a solder that is melted by energy emitted by the inductor.

Described herein are methods of constructing a part using BMG layer by layer. In one embodiment, a layer of BMG powder is deposited to selected positions and then fused to a layer below by suitable methods such as laser heating or electron beam heating. The deposition and fusing are then repeated as need to construct the part layer by layer. One or more layers of non-BMG can be used as needed. In one embodiment, layers of BMG can be cut from one or more sheets of BMG to desired shapes, stacked and fused to form the part.
摘要:
A method and a device (1) for bonding a metal fairing (6) to protect a leading edge of an aircraft airfoil (7), the metal fairing (6) is designed to be bonded against the airfoil (7) with the help of an adhesive (9). The bonding device (1) is remarkable in that it includes a rigid yoke (2) having inserted therein induction heater elements (30) for heating the metal fairing (6).
摘要:
A covering device for covering an area of an organic substrate, with a connecting zone between a closure cap and the substrate. It is proposed that the connecting zone includes, at least in certain areas, a heating element for heating the connecting zone during the creation of a connection between the closure cap and the substrate. Also provided is an organic substrate with a covering device and a production method for producing a covering device.
