A device, use of the device and method for setting a specific operating position of an apparatus component, such as a wire feed of a welding installation. The apparatus component can be moved, in particular linearly displaced, to set the specific operating position and, after being moved into the specific operating position, can be fixed in place in said position for operation. The device includes a positioning element that has a modifiable surface on which the specific operating position can he preset for operation; and a setting aid that comprises at least one region interacting with the modifiable surface of the positioning element, and which is embodied to lie against the apparatus component.

A device for welding may include a track configured to surround a workpiece. The device for welding may also include a cart configured to contact the track such that the track guides the cart around the workpiece. The cart may include a frame and a welding torch receptacle. The welding torch receptacle can be attached to the frame. The welding torch receptacle may be configured to maintain a tip of the welding torch at a set distance away from the workpiece while the cart moves around the workpiece.

Apparatuses configured to be deployed from mobile welding repair vehicles for the repair of railroad trackwork allow a welding system to be stored and deployed from the mobile welding repair vehicles. The apparatuses deploy from the vehicles on a slide system and are supported by one or more legs, the system having 180-degree or greater rotation for full reach of railroad trackwork for welding repair thereof. Methods of using the same are further provided.

A moveable head of a computer numerically controlled machine may deliver electromagnetic energy sufficient to cause a first change in a material at least partially contained within an interior space of the CNC machine. A feature of the material may be imaged using at least one camera present inside the interior space to update a position of the material, and the moveable head may be aligned to deliver electromagnetic energy sufficient to cause a second change in the material such that the second change is positioned on the material consistent with the first change and with an intended final appearance of the material. Methods, systems, and article of manufacture are described.

A computer numerically controlled machine may include a movable head configured to deliver electromagnetic energy to a part of a working area in which the movable head may be commanded to cause delivery of the electromagnetic energy. The interior space may be defined by a housing and may include an openable barrier that attenuates transmission of light between the interior space and an exterior of the computer numerically controlled machine when the openable barrier is in a closed position. The computer numerically controlled machine may include an interlock that prevents emission of the electromagnetic energy when detecting that the openable barrier is not in the closed position. The commanding may result in the computer numerically controlled machine executing operations of a motion plan for causing movement of the movable head to deliver the electromagnetic energy to effect a change in a material at least partially contained within the interior space.

A system can include a head of a computer numerically controlled machine configured to deliver electromagnetic energy sufficient to cause a change in a material at least partially contained within an interior space of the computer numerically controlled machine. The system can further include an optical system comprising a plurality of optical elements in the computer numerically controlled machine. The plurality of optical elements can be oriented at a fixed angle to each other to deliver the electromagnetic energy from the head to the material.

An apparatus for surface processing of cylindrical bodies including a work station (100) for rotatably supporting the cylindrical body (1), a laser emitter (600) movable along a main direction (X) parallel to the rotation axis (K) of the cylindrical body (1) and according to an auxiliary direction (Z) transverse to the main direction (X), a distance sensor (700) for detecting a control parameter relative to a distance of the sensor or the laser emitter (600), and a control unit (15) configured for commanding a movement of the laser emitter (600) and of the distance sensor (700) along said main direction (X), commanding the emission of a laser beam directed towards a surface of the cylindrical body (1), executing a correction procedure adapted to compensate for the eccentricity of the cylindrical body (1) with respect to said rotation axis (K).

A welding device (1) has a contact tip (2) with an elongated feeding means for feeding a welding wire (4), wherein the contact tip (2) is arranged on or in a nozzle holder (6). A feed device (100) transfers the welding wire (4) from a first orientation into a second orientation, wherein in the first orientation the welding wire (4) is fed to the feed device (100), and in the second orientation the welding wire (4) is led out of the feed device (100) to the nozzle holder (6). A plurality of welding wire cores (8, 10) are introduced into a conduit element (200) via a first conduit element end (202). The welding wire (4) which is guided in the welding wire cores (8, 10) can be guided out of the conduit element (200) via a second conduit element end (204). The welding wire (4) which is guided out of the conduit element (200) via the second conduit element end (204) can be fed into the feed device (100), especially while in the first orientation.

A chassis welding device for welding brackets as standard members to a body of a chassis includes a frame, a first transferring member, a plurality of loading mechanisms, a plurality of carriers, a conveying member, a shifting member, and a spot welder. The loading mechanism transfers standard members to individual preset positions on the carrier to face the solder joints on the standard members away from the carrier. The first transferring member transports the carrier to the shifting member. The shifting member transfers the carrier from the first transferring member to the spot welder. The conveying member transfers the body into contact with the solder joints. The spot welder applies heat to melt the solder joints to bond the standard members to the body.

Disclosed is a welding jig for welding an electrode lead of a battery cell and a sensing bus bar of a bus bar assembly to each other, and the welding jig includes a jig body disposed above the electrode lead and the sensing bus bar during the welding; and a positioning guide unit coupled to the jig body and configured to make a step correction in at least three directions when the electrode lead and the sensing bus bar are welded.
