A method for producing workpiece parts from a plate-shaped workpiece in a processing machine or laser processing machine includes positioning and holding the workpiece on a workpiece support by clamping devices. A plurality of workpiece parts are cut out of the workpiece with a process beam. The process beam is moved relative to the workpiece support by a processing head and/or the workpiece is moved relative to the workpiece support by the clamping devices. A cutting process for processing the workpiece to produce the workpiece parts is interrupted at least once by a relaxation step for the workpiece. During the relaxation step at least one clamping device is released to relax the workpiece. The at least one clamping device is closed following the relaxation and before continuing the cutting process. A data processing program and a processing machine for producing the workpiece parts are also provided.

A method for purging air from a structure to be joined by welding by feeding a liquid cryogen to the structure. The liquid cryogen will enter the structure, warm up and enter the gaseous phase very rapidly. The gaseous cryogen will displace the air that is present in the structure out of the structure and reduce the content of oxygen in the structure to about 10 parts per million when welding can begin.

Apparatuses and methods for repairing a defect in a nuclear reactor are provided. The apparatus includes a body for insertion in a tubular structure, the body includes: an end effector having a weld torch operable to deposit weld material by forming molten weld droplets and depositing the weld droplets the tubular structure. A drive unit includes a brace for selectively anchoring against said tubular structure; at least one linear actuator for moving the apparatus relative to the brace; and a rotational actuator coupled to rotate the weld torch. The method includes inserting a repair apparatus into tubular structure of the nuclear reactor; moving the repair apparatus to a defect location; depositing a protective weld layer over the defect by sequentially depositing weld droplets atop a weld pool on the tubular structure, wherein the protective weld layer bonds to the tubular structure surrounding the defect.

Power system radiators and power systems having radiators are disclosed. An example power system includes: an engine; a generator configured to generate electrical power from mechanical power provided by the engine; power conversion circuitry configured to convert the electrical power from the generator to welding-type power; and a housing enclosing the engine, the generator, and the power conversion circuitry; and a radiator assembly configured to cool the engine and comprising a heat exchanger oriented substantially horizontally when the power system is installed.

A purge system useful in welding applications to provide a shielding or purging gas to a weld site, preferably of a tube, pipe or construction, while also providing controlled release of an exhaust gas and pressure relief through the use of a permeable body. The purge system is also flame resistant allowing use in close proximity to the weld site. The design facilitates ease of insertion, holding and retraction in a tube, pipe or other construction.

Systems and methods for welding asset tracking are disclosed. In some examples, a welding asset tracking system may comprise an asset tracking network of tags, hubs, and/or gateways retained by welding assets within a welding area. The asset tracking network may obtain and/or communicate to an asset tracking server welding data related to one or more of the welding assets, as well as position data obtained via an internal and/or external positioning system. In this way, the welding asset tracking server may continually receive updated information regarding each welding assets identity, location, and/or use. The asset tracking server may additionally send a command to a selected welding asset that causes an interface of the selected welding asset to emit an output that enables an operator to physically identify the welding asset.

The invention relates to an exchangeable wearing part of an arc welding torch, said wearing part being intended to be arranged in the region of an end, provided for carrying out a welding process, of the arc welding torch, wherein the wearing part is provided with a thread on an outer lateral surface and/or on a boundary wall of a recess, an improvement in heat transfer properties and, when such components are conducting, also improved power transmission properties are intended to be achievable. To this end, the invention proposes that, in the direction of a longitudinal axis of the wearing part, a first conical portion, having the thread provided for fastening the wearing part, of the lateral surface or of the boundary wall is followed, on the same lateral surface or boundary wall, by a thread-free second conical portion of the lateral surface or of the boundary wall.

An operating device of a welding system is provided with a display means for visually displaying set parameter values of the welding system, and comprises input means by which parameters of the welding system can be changed. An operating device includes a plurality of input means arranged outside the display means, is provided. The input means is designed as soft keys, wherein, each of the soft keys can be assigned parameters of the arc welding method or functions, via operation of the operating device, due to the fact that the display means is designed as a touch-sensitive touchscreen and the respective soft key can be assigned a specific parameter or a specific function by selection from a predefined selection of parameters or functions displayed on the display means and, after selection, the respective parameter can be changed or the function can be applied by actuating the respective soft key.

Systems and methods for automatically regulating the flow of fumes suctioned through a welding fume gun are provided. In certain embodiments, an automatic flow control assembly includes a vacuum system configured to suction a vacuum fume flow through an internal passage of a welding fume gun. The automatic flow control assembly also includes a sensor configured to measure a parameter related to the vacuum fume flow. The automatic flow control assembly further includes a flow regulation device configured to regulate an ambient air flow introduced into the vacuum fume flow. In addition, the automatic flow control assembly includes control circuitry configured to control the flow regulation device based at least in part on the measured parameter related to the vacuum fume flow.
