Ozone supply unit and method for providing ozone for a flame burner apparatus and/or for an oxygen cutting apparatus

The invention relates to a method for producing, in particular generatively producing, and coding a three-dimensional component. Said method comprises the following steps: providing a starting material, supplying a process gas to the starting material, melting the starting material by means of a heat source, and repeating the aforementioned steps. The method according to the invention is characterized in that, at least at a predetermined time interval during the melting of the starting material, a coding component or a coding gas containing a coding component is added to the process gas such that the use of the coding component in the finished object is detectable, and coding information is logged which describes the coding information and the location thereof in the component.

Method and device in particular for generatively producing and coding a three-dimensional component

The invention relates to a method for coding metal powder. Said method comprises the following steps: providing a melt, forming a melt stream, spraying the melt stream by means of a spraying fluid, and forming metal powder particles from the melt stream. The method is characterized in that, during the spraying of the melt and/or the spraying fluid, a coding component or a coding gas is added in such a way that the use of the coding component in the metal powder can be detected, wherein the gaseous coding component comprises one or more isotopes of at least one gas and the fraction of the at least one isotope is changed in comparison with the naturally occurring fraction of said isotope in the gas and/or wherein the gaseous coding component contains gaseous alloying elements.

Method and device for producing and coding metal powder

A method for flame straightening is disclosed, wherein acetylene with oxygen is combusted by means of a burner to yield a flame, and the flame is directed onto a workpiece so as to heat the workpiece, wherein an electric field is applied between the burner and the non-melting workpiece which is electrically conductive, or the electric field is applied between the burner and a non-melting electrode arranged on the non-melting workpiece side to reduce NOx emission.

Method for flame straightening and burner assembly for this purpose

A method of gas-shielded metal arc joining using a consumable electrode having an alternating polarity (GMA-AC). A shielding gas containing argon is used to improve process stability and working speed.

Metal-protective gas-joint with changeable polarity

A method of gas-shielded metal arc joining using a consumable electrode having an alternating polarity (GMA-AC). A shielding gas containing helium is used to improve process stability and working speed.

In joining heterogeneous materials that differ in their melting points, a shielding gas mixture with active gas content is utilized. In particular, the shielding gas mixture contains helium and active gasses in the vpm range (0.005 to 0.5% by volume). These shielding gases to lead to the production of high quality joints when joining aluminum and steel.

Process for making heterogeneous joints under shielding gas

In a process for the production of a shielding gas mixture argon is withdrawn from a liquid argon supply, vaporized and mixed with a gas premix. The gas premix contains helium and/or argon and a doping gas. A shielding gas mixture prepared this way is outstandingly suited, especially because of the helium content, for arc welding of aluminum and aluminum alloys.

Process for the production of a shielding gas mixture

A shielding gas for gas shielded metal-arc welding or brazing with multiple (in particular 2) wire electrodes, one common melting bath, and multiple power sources. Such shielding gases contain, for example, a small percentage of carbon dioxide or doping gas and possibly hydrogen, 10%&#x2013;75% helium, with the remainder argon. The process is applicable to aluminum materials and low alloy or high alloy steels, for example.

Tandem welding shielding gases

A hybrid welding from a combination of laser beam welding with gas-shielded welding by electric arc uses at least two electrodes are used. The electrodes can be flooded by a common shielding gas curtain or separately or in groups. The hybrid welding increases the possibility of influencing the welding process and especially provides improved possibilities for automation.
