Abstract:
Hybrid manual and automated welding systems and methods are described. A hand-held welding tool is manually positioned to engage a workpiece. A weld is started from an initial position based on a first manual operator event. A welding heat source is automatically or autonomously moved along the weld relative to the workpiece from the first position to a second position relative to the workpiece during welding.
Abstract:

A drive chain is mounted to the base and aligned generally with the neutral bending axis. A system includes a flexible track and an apparatus. The flexible track includes a base configured to be generally flexible along the neutral bending axis of the flexible track and generally rigid in a torsional direction, the torsional direction being generally rotated about the neutral bending axis. The flexible track further includes a drive chain mounted to the base aligned generally with the neutral bending axis. The apparatus includes a drive sprocket engaged with the drive chain and a motor and gear box operably associated with the drive sprocket.
Abstract:
Die Erfindung betrifft ein Verfahren zur Reparatur eines Schadens an einem metallischen Substrat (1), bei dem eine Vertiefung (2) im Bereich des Schadens angefertigt wird und ein metallisches Füllstück (3) mit wenigstens einem konvexen, gekrümmten Abschnitt in die genannte Vertiefung (2) eingelegt wird. Dabei wird der genannte gekrümmte Abschnitt der Vertiefung (2) zugewandt und das Füllstück so eingelegt, dass es den Boden der Vertiefung (2) berührt, zum Rand (4) der Vertiefung (2) jedoch wenigstens bereichsweise ein Abstand vorgesehen wird. Danach wird das Füllstück (3) mit dem Substrat (1) verschweißt.
Abstract:
The invention relates to a carrier (1) for carrying and moving a welding torch, cutting torch or other corresponding torch (6) at a worksite, which carrier (1) comprises a frame, which is arranged movable on a base, as well as a bracket arrangement (5) of the torch (6), arranged attachably to the frame, for attaching the torch (6) detachably in the carrier (1), which bracket arrangement comprises connection means (5a) for connecting the bracket arrangement (5) to the carrier (1), attachment means (6a) for attaching the torch (6) to the bracket arrangement (5), and one or more interconnection parts (17) for interconnecting the connection means (5a) and the attachment means (6a) to each other, which attachment means (6a) can be moved in relation to the connection means (5a), as well as locking means (7a), which are functionally combined with the attachment means (6a) and which are adapted to lock the torch (6) in place in the attachment means (6a) as well as to lock the attachment means (6a) into different positions in relation to the connection means (5 a) such that the distance of the torch (6) in relation to the work subject and the position of the torch (6) in relation to the connection means can be locked in place.
Abstract:
Methods and apparatus for manufacturing operations are disclosed. In one embodiment, an apparatus for supporting a tool relative to a surface of a workpiece includes a base adapted to be attached to the workpiece, a tool support coupled to the base, and a biasing device coupled to both the base and the tool support. The tool support is moveable relative to the base along a translation axis, and the biasing device is biasable along a biasing axis that is at least partially along the translation axis. The biasing device is adapted to at least partially counterbalance a force (e.g. a gravitational force) exerted on the tool support along the translation axis.
Abstract:
This invention relates to a welding carriage operable to drive across a surface of a work piece having a joint to be welded. The welding carriage comprises a number of wheels, where each wheel is pivotal around an axle and where each wheel is a magnetic wheel; the welding carriage further comprises means for supporting a welding device wherein at least one of the wheels can be flexed inwardly or outwardly so that the welding carriage can travel over curved surfaces.The welding carriage can travel over magnetizable surfaces having any direction, e.g. orientation in space. The welding carriage can carry a laser sensor arrangement arranged to detect the position as well as the direction of a joint to be welded, so that the welding carriage is applicable for performing fully automated welding.
Abstract:
Apparatus for remotely placing and welding a patch over an underwater breach in the hull of a ship. The apparatus is lowered into position over the side of the ship by a winch and cable, then held against the ship's hull (1) by electromagnets (13). The apparatus has a generally streamlined frame (2) containing a chamber (10) within which a patch plate (39) is carried. Wheels (11) are disposed on the frame to permit the frame to be driven along the hull and positioned over the breach. The patch plate (39) is then moved into position against the hull and welded into place. Operation of the apparatus is viewed through video cameras and is remotely controlled by an operator on board the ship.
Abstract:
The present application provides a mobile welder (100) that does not rely exclusively on a track to define the path of the welder (180). The system (100) is adapted to move along a work piece (W), the mobile welder including a chassis (120) supporting a motor assembly, a travel assembly (140) attached to the chassis (120) and adapted to support the chassis (120) over a portion of the work piece (W), wherein the motor is coupled to the travel assembly (140) to selectively cause the chassis (120) to move relative to the work piece (W); a controller connected to the motor assembly to control movement of the chassis (120) relative to the work piece (W), a chassis holder (130) connected to the chassis (120), the chassis holder (130) being adapted to provide a force holding the chassis (130) a selected distance from the work piece (W); and a welder (180) supported on the chassis (130), the welder including an implement (185) adapted to perform a welding operation, wherein the implement (185) is supported on the chassis (120) at a location where the implement (185) and the chassis (120) define an uninterrupted line of sight from the implement to the work piece (W), wherein the chassis holder (130) is spaced from the line of sight a distance sufficient to prevent the chassis holder (130) from interfering with the welding operation.
