Processes, devices, and systems for beam processing of plate-shaped or tubular workpieces are provided. The processes include: a) carrying out at least one cutting procedure for producing a cutting gap along a cutting line that extends at least partially along a contour of a workpiece part to be produced from the workpiece, and b) carrying out at least one finishing procedure for finishing the workpiece along at least one part of the cutting gap, during which the workpiece part is not completely cut out. The cutting procedure includes moving a beam head for guiding a processing beam above the workpiece along the cutting line from a first cutting position to a second cutting position. The finishing procedure includes moving the beam head over the workpiece, and the processing beam is guided along a finishing line from a first finishing position to a second finishing position.

A method and machine for cutting and removing a workpiece part from a plate-shaped material includes cutting the workpiece part with a beam or jet directed onto the material and separating the workpiece part and material. The workpiece part is removed as a scrap skeleton removal part. The cut-free workpiece part is lifted out of a workpiece supporting plane by a lifting device and removed by a gripping device, or the cut-free workpiece part is removed downwards from the plane through a gap between workpiece supporting surfaces by an ejection device, or gravity removes the cut-free workpiece part downwards through the gap. Before cutting the workpiece part free, a sacrificial part adjoining the workpiece part and partially having a common cutting line with the workpiece part is cut free from the material before cutting the workpiece part free in the material or scrap skeleton.

A jacketed consumable cartridge is provided for a liquid cooled plasma arc torch. The jacketed consumable cartridge comprises an electrode, a swirl ring securely affixed to and disposed circumferentially about a distal end of the electrode, and a nozzle securely affixed to the swirl ring, the nozzle disposed circumferentially about the distal end of the electrode with a portion of the swirl ring located therebetween. The cartridge also comprises a cartridge jacket securely affixed to and disposed circumferentially about a distal end of the nozzle and a shield securely affixed to and disposed circumferentially about a distal end of the cartridge jacket. A proximal end of the cartridge jacket is adapted to extend (i) axially past a proximal end of the shield and (ii) radially beyond a radial extent of the shield.

In some aspects, material processing head can include a body; an antenna disposed within the body; a first tag, associated with a first consumable component, disposed within a flux communication zone of the body at a first distance from the antenna, the first tag having a first resonant frequency; and a second tag, associated with a second consumable component, disposed within the flux communication zone of the body at a second distance from the antenna, the second tag having a second resonant frequency that is different than the first resonant frequency, where the first and second resonant frequencies are tuned based upon at least one of: i) a difference between the first distance and the second distance; or ii) a characteristic (e.g., shape) of the flux communication zone in which the first tag and/or the second tag is disposed.

Method and device for marking a workpiece surface (2A) of a metal workpiece (2), in which a welding torch (3) comprising a welding wire electrode (4) is guided along the workpiece surface (2A) to be marked and meanwhile a wire end (4A) of the welding wire electrode (4) is moved towards and away from the work-piece surface (2A) to be marked, wherein an electric voltage (U) present at the welding wire electrode (4) and/or an electric current (I) flowing through the welding wire electrode (4) bring about electric sparks, which bring about material removal and/or material alteration at the workpiece surface (2A) of the metal workpiece (2) to mark the workpiece surface (2A).

A metal cutting device, including a main body, a plurality of legs pivotally disposed on at least a portion of the main body to suspend the main body over a surface, a handle assembly removably connected to at least a portion of the main body to facilitate gripping thereof, and a torch removably connected within at least a portion of the main body to cut the surface in response to contact with the surface.

Approaches herein provide a torch handle including a pneumatically controlled jaw operable to engage an electrode. In one approach, a system is provided for distributing gas within the torch handle, the system including a pneumatic cylinder within a main housing of the torch handle. The pneumatic cylinder is coupled to a shaft for actuating first and second members of the jaw. The system further includes a gas passageway through the main housing, the gas passageway extending to an exit orifice disposed within the second member. A flow controller, including first and second valves, is operable to direct a flow of a gas to either the pneumatic cylinder or the gas passageway. In one approach, the first member is actuated towards the second member when the gas is directed through the gas passageway, and actuated away from the second member when the gas is directed to the pneumatic cylinder.
