A mobile welding system that does not rely exclusively on a track to define the path of the welder. The present invention generally provides a mobile welder adapted to move along a work piece, the mobile welder including a chassis supporting a motor assembly; a travel assembly attached to the chassis and adapted to support the chassis over a portion of the work piece, wherein the motor is coupled to the travel assembly to selectively cause the chassis to move relative to the work piece; a controller connected to the motor assembly to control movement of the chassis relative to the work piece; a chassis holder connected to the chassis, the chassis holder being adapted to provide a force holding the chassis a selected distance from the work piece; and a welder supported on the chassis, the welder including an implement adapted to perform a welding operation, wherein the implement is supported on the chassis at a location where the implement and the chassis define an uninterrupted line of sight from the implement to the work piece, wherein the chassis holder is spaced from the line of sight a distance sufficient to prevent the chassis holder from interfering with the welding operation.

Provided is an apparatus for forming a tab from a moving original sheet with a laser beam. This apparatus is a tab forming apparatus in a tabbed electrode sheet producing apparatus (100) for moving, in one direction, an original sheet (1) including an electrode portion (1a) obtained by applying an active material layer to a long metal foil (4) and an ear portion (1b). This tab forming apparatus includes: a laser emission device (50) configured to apply a laser beam (L1) to the moving ear portion (1b) to cut out a tab (5) connected to the electrode portion (1a); an ear portion separating portion (70) provided at a position above or below a moving plane on which the electrode portion (1a) moves, on a downstream side of an irradiation point (Pm) of the laser beam (L1), so as to cause a take-up angle (α) to occur at the irradiation point (Pm) between the ear portion (1b) from which the tab (5) has been cut out and the moving plane; and an ear portion collection portion (80) configured to collect the ear portion (1b) in synchronization with the movement of the original sheet (1), while applying tension to the ear portion (1b) from which the tab (5) has been cut out with the laser beam L1.

The invention refers to a machine for 3D processing of volumetric metal objects with random shapes and sizes, in particular for thermal and/or laser cutting of holes and random contours in metal cabinets in their assembled state. The machine consist frame /1/, on the horizontally oriented beams /5/ are fixed linear guide ways, on which are placed two vertical oriented carriages /6/, wherein at their upper end the carriages /6/ are connected with a cross beam /7/ oriented toward axis X and perpendicular to axis Y, and on the cross beam /7/ are mounted at least two linear guide ways to which a horizontally oriented carriage /8/ is connected, with the possibility of movement along the axis X, as to the carriage /8/ is mounted a ram /9/, which move in the carriage /8/ with the possibility of movement in the vertical direction along axis Z.

Provided are a welding apparatus and a method, including a welding torch, a wire nozzle, a support stand that supports the welding torch and the wire nozzle with a predetermined distance therebetween, and a first support mechanism that supports the support stand so that the support stand is rotatable around a first support axis that is along a direction in which the welding torch and the wire nozzle are arranged.

The invention described herein generally pertains to systems and methods related to repeatable and accurate setting of welding torch lead and lag positions, particularly with orbital welding systems. Specifically, a torch is coupled with a lead-lag coupler having a stop lug. A stop set with a stop pin is rotated to a desired position of lead or lag and secured. The lead-lag coupler, and torch which rotates therewith, are then unsecured and rotated until the stop lug contacts the stop pin. In this position, the torch is maintained at the desired angle. The stop pin remains in place throughout operation(s) to permit quick, accurate return to the desired angle if the torch is temporarily moved out of position.

In some aspects, autonomous motion devices configured to operably connect to a plasma torch of a plasma cutting system can include: a body to support a power supply of the plasma cutting system and move relative to a workpiece; a torch holder connected to the body and configured to position a plasma arc torch tip of the plasma torch relative to a region of the workpiece to be processed; a drive system to translate the body supporting the power supply and torch autonomously relative to a surface of the workpiece during a plasma processing operation; and a processor in communication with the drive system and configured to communicate with the power supply, the processor being configured to control the translation of the body relative to the workpiece in accordance with the plasma processing operation.

A robotic welding equipment station to detect deviation of a tool center point of a welding torch. The station is provided with pairs of light emitting and detecting devices to emit and detect two separate light beams. The pairs of light emitting devices and detectors are oriented at an angle and spaced apart from each other such that the two light beams are at an angle to one another and the weld wire electrode is able to simultaneously interrupt both light beams when there is no deviation in a tool center point. The spacing prevents the weld wire electrode from interrupting both light beams when an increasing deviation of the tool center point propagates along the length of the weld wire electrode. First and second output signals generated by the first and second light detectors are received by a means for detecting deviation of the tool center point.

The present disclosure teaches systems and methods for robotic welding of studs onto the surface of I-beams. These systems and methods will find industrial applicability in, for example, the steel erection industry.

A plasma cutting system for measuring or monitoring the voltage between a plasma torch and the material being cut to determine a voltage or voltage signature and comparing that measurement against predetermined values to indicate that an initial pierce of the material is complete, and based on the measurement, moving the torch or the material to a different location for additional cutting. The system further provides a Fix Drawing Tool, which will automatically detect and fix gaps or overlaps in a drawing that are very difficult to find visually. These gaps and overlaps become a problem when trying to make a proper toolpath because a CAM program requires a clean, closed shape. The system also provides a Dynamic Corner Looping system, which automatically adjusts with the feed-rate and accelerations of the toolpath and plasma machine, eliminates unwanted dross, sharpens corners and minimizes material loss. A pendant tethering system is also disclosed for managing control of a CNC machine remotely. Additional disclosed functionality includes a data collection system, a manual hand wheel with 3D simulation and a multiple fabrication head management system.

A resin pipe 30 and a resin member 31 are fixed to a setting portion 5 provided on the front side of a base 6, and a timing pulley 13 which is provided on the back side of the base 6 and to which a light emission unit 3 is attached is rotated. As a result, the light emission unit 3 applies laser light 20 to a junction 32 between the resin pipe 30 and the resin member 31 while revolving around the junction 32. This makes it easy to fuse and join the entire outer circumferential surface of the resin pipe 30 with the entire inner circumferential surface of the resin member 31, which are variously shaped and sized.
