  • Patent number: 10485086
    Abstract: The invention relates to a single or multipart insulating component for a plasma torch, particularly a plasma cutting torch, for electrical insulation between at least two electrically conductive components of the plasma torch, characterized in that the insulating component consists of an electrically non-conductive and easily thermally conductive material, or at least one part thereof consists of an electrically non-conductive and easily thermally conductive material. The invention further relates to assemblies and plasma torches having the same and to a method for processing, plasma cutting and plasma welding.

  • Publication number: 20190039175
    Abstract: The present invention relates to an apparatus and a method for thermal processing within a processing region (1) at a workpiece surface (2) by means of a laser beam (6) emitted by at least one radiation source (5). Arranged in the beam path of the laser beam (6) between the at least one radiation source (5) and the processing region (1) on the workpiece surface (2), there is at least one element (10, 11, 12) by means of which the intensity of the laser beam (6) is modifiable in a locally defined manner within the processing region (1). As an alternative or in addition thereto, the intensity of at least one of the laser beams (6) is modifiable in a locally defined manner within the processing region (1) by a defined actuation of the plurality of radiation sources (5) such that a locally defined distribution of the intensity of the laser beam (6) striking the workpiece surface (2) is achievable within the processing region (1).

  • Patent number: 10201068
    Abstract: The invention relates to a method for the plasma cutting of workpieces. It is the object of the invention to provide possibilities with which improved cutting surfaces can be achieved in plasma cutting which do not require any reworking, or at least only a reduced reworking. In the method in accordance with the invention, a plasma cutting torch having at least one torch body, an electrode and a nozzle is used and the plasma jet is inclined or deflected at least before the traveling over of a workpiece edge at an angle ? with respect to the axis aligned perpendicular to the workpiece surface such that the emission position of the plasma jet from the workpiece is arranged at a spacing in the feed movement direction which is at most half the amount than is the case with a plasma jet incident perpendicular on the workpiece surface.

  • Publication number: 20170332469
    Abstract: The invention relates to a plasma cutting arrangement having at least one plasma cutting torch which is formed by a torch body, an electrode and a nozzle having a nozzle bore. An outer contour AK of the plasma cutting torch is present in cross-section with respect to a longitudinal axis which is aligned perpendicular through the nozzle bore. A smallest spacing between the longitudinal axis extending through the center of the nozzle bore of the nozzle and the radially outer margin of the outer contour AK is observed in at least one axial direction and corresponds at a maximum to ¾ of the length of a largest spacing d between the central longitudinal axis extending through the center of the nozzle bore of the nozzle and the radial outer margin of the outer contour AK.

  • Patent number: 9743505
    Abstract: The invention relates to a plasma torch, preferably to a plasma cutting torch, in which a plasma gas PG1 and/or PG2 flows through at least one feed through a housing of the plasma torch gas up to a nozzle opening. A hollow space connected to the feed(s) is also present within the housing and a valve which opens and closes an opening is arranged at the opening at said hollow space and a leading off of plasma gas PG1 and/or PG2 out of the feed(s) up to the nozzle opening can be achieved in the open state of this valve.

  • Patent number: 9462671
    Abstract: The invention relates to an electrode structure for plasma cutting torches, wherein a recess or borehole open at one side in the direction of a workpiece to be processed is formed in an electrode holder or in a holding element for receiving an emission insert, in which recess or borehole the inserted emission insert can be fastened in a force transmitting manner, in a shape-matching manner and/or with material continuity. At least one pressure equalization passage and/or an at least temporarily active pressure equalization passage is present between a hollow space formed in a recess or borehole and the emission insert and the environment through the emission insert and/or between an outer jacket surface region of the emission insert and the inner wall of the recess or borehole, which is formed in the holding element or in the electrode holder (7.1).

  • Patent number: 9073141
    Abstract: The invention relates to an electrode for plasma torches for plasma cutting and to a use of the electrode for said plasma torch. The electrode in accordance with the invention for plasma cutting torches is formed from an electrode holder and from an emission insert which are connected to one another in a force-fitted and/or shape-matched manner. The emission insert has at least one section along its longitudinal axis which is arranged between two other sections or next to a section which has a reduced outer diameter in a rotationally symmetrical design of the emission insert or has a reduced cross-sectional surface in a non-rotationally symmetrical emission insert with respect to the other section(s).
