Abstract:
A welding system (300) is provided, in which two electrodes (E1, E2) are directed at a joint between two work pieces (WP1, WP2) and the electrodes (E1, E2) are energized with DC pulse or AC welding waveforms at a controlled waveform phase angle. The system (300) includes a synchronizing controller (40) to synchronize the welding waveforms, and a work point allocation system (12) provides one or more work point values to the welding machines to provide synergic control of the welding according to a user selected system work point value or parameter. The system and the corresponding method further provide for synchronized work point value modulation for the opposite sides of a dual fillet weld. The system (300) and the method further provide a high energy heat source (310) that directs intense heat at a portion of the weld joint to improve weld penetration.
Abstract:
A method of manufacturing a furcated composite post (1) comprising at least two strips (7, 8) that are joined together along their length in a furcated manner. The method comprises the steps of feeding one or more of the strips (7, 8) at a set rate to working rolls of a roll mill for profile rolling to a desired cross section/profile, feeding the strips (7, 8) at the same set rate to positioning rolls for holding the strips (7, 8) in a correct orientation for joining, and joining the strips together, preferably by welding the strips (7, 8) along their length.
Abstract:
A beam working apparatus, includes opposed vice assemblies for holding and rotating a beam about a long axis thereof and a number of gantries that are arranged for translational motion along the beam. At least one tool head mount is provided fast with each of the gantries for a tool for working upon the beam. A number of motors are provided to selectively rotate the vice assemblies and move the gantries in order that the apparatus can be operated by a computerized control system.
Abstract:
There is provided a three-dimensional laser beam machining apparatus for a long workpiece (W 1 ), which includes an automatic loading device (100) for a large variety of materials that feeds materials to a three-dimensional laser beam machine. The automatic loading device (100) for a large variety of materials has a bundle type material loading device (120). A bundle type material (W 1 ) is a round pipe or a polygonal pipe, and the posture thereof around the axis line is aligned automatically when the material is conveyed by a roller conveyor (140). The front material stopped by a stopper (150) is sent out to an inclined conveyor (180) over the stopper (150) by means of a swing arm (170). The bundle type material (W 1 ) as well as a versatile type material, the posture of which around the axis line is not aligned automatically, are set on a receiving member (210) of a common conveyor (200) and sent to the three-dimensional laser beam machine by the operator.
Abstract:
The invention relates to a method for manufacturing a structural element intended for aeronautical construction, typically a wing spar comprising a web and one or more adjacent stringer elements, comprising the following steps (i) at least a first and second metal block are made available, the limit of elasticity under compression of the first metal block being greater than that of the second metal block, (ii) the first metal block comprises a first web portion and at least one stringer element the second metal block comprises a second web portion placing the first and second web portions end-to-end over their entire common length. The invention permits the manufacture of bifunctional or multifunctional structural elements comprising several assembled parts but whose stringers have a mechanical strength greater than that obtained by traditional methods .
Abstract:
Die Erfindung betrifft eine Vorrichtung zum Ausrichten und Schweißen von drei oder vier Blechen eines Kastenträgers, insbesondere eines Hauptträgers für Krane, der mindestens zwei in Kastenträgerlängsrichtung beabstandete, an den Innenseitenflächen der Bleche angeschweißte plattenförmige Querschotten aufweist, mit einem nach unten offenen U-förmigen Fertigungsrahmen, der auf zwei parallelen Schienen zwangsgeführt über den Kastenträger hinweg in Kastenträgerlängsrichtung verfahrbar ist und der längs- und/oder vertikalbeabstandete, den Seitenblechen unmittelbar gegenüberliegende und zumindest zeitweise aktivierbare Magnete trägt und mit mehreren am Fertigungsrahmen angeordneten Magneten in Fahrtrichtung nachgeordneten Schweißvorrichtungen, mittels derer die Bleche im Verlauf des Fahrweges jeweils mittels Kehlnähten miteinander paarweise verschweißbar sind. Um eine Vorrichtung anzugeben, bei der das Heften der Bleche vor dem Schweißen entfallen kann, wird vorgeschlagen, dass die Magnete (6) als im Fertigungsrahmen (1) drehgelagerte Rollen ausgebildet sind, deren Drehachsen jeweils in einer Ebene quer zur Kastenträgerlängsrichtung und bezüglich des ausgerichteten unmittelbar gegenüberliegenden Seitenblechs (8a) parallel zu diesem verlaufen.
