摘要： A metal jet cutting system, which includes a jetting heat, a heater and a power source, is used for modifying a workpiece. The jetting head includes a crucible and an inlet for receiving a feed stock of a conductive material. The heater melts the conductive material in the crucible to provide a conductive fluid, which exits the jetting head via an outlet. The power source, which is in electrical communication with the conductive fluid, increases the temperature of the conductive fluid. The conductive fluid is applied to the workpiece to modify the workpiece.

摘要： An output structure for material processing apparatus facilitates field replacement of consumable components, while maintaining important alignments. Contoured surfaces within the output structure mate with corresponding contoured surfaces on the consumable components, thereby facilitating alignment of the consumable components with an axis of the output structure. Material processing apparatus employing such surfaces include lasers and plasma arc torches and, with proper alignment, apparatus performance is improved. Typical consumable components include electrodes, swirl rings, nozzles, and shields. The consumable components can be axially translatable with respect to each other, thereby promoting contact starting of a plasma arc torch. An installation tool for consumable components also serves to align the components with an axis of the output structure.

摘要： A configurable baffle to configure fluid flow through a nozzle. To improve the quality and accuracy of processing apparatus used in the cutting, welding, and heat treating of materials, a self-aligning nozzle includes a configurable baffle. This configurable baffle can be a metallic grid (e.g., a screen) or other type of membrane (e.g., porous, permeable, etc.). During its initial use in the processing apparatus, this configurable baffle is tailored with an energy beam, such as a laser beam or plasma jet, to create an optimal fluid flow velocity profile. When the configurable baffle deteriorates from use, it is easily replaced by another baffle or by using an in situ replacement mechanism. To ensure proper alignment between the nozzle and the energy beam, mating contoured surfaces are used among adjacent components. Threaded surfaces can also be employed to assist in achieving the proper coaxial alignment.
摘要翻译：配置挡板以配置通过喷嘴的流体流动。为了提高用于材料的切割，焊接和热处理的加工设备的质量和精度，自对准喷嘴包括可配置的挡板。该可配置挡板可以是金属网格（例如，屏幕）或其它类型的膜（例如，多孔，可渗透等）。在其最初使用处理装置期间，该可配置的挡板利用能量束（例如激光束或等离子体射流）来定制，以产生最佳的流体流速分布。当可配置挡板因使用而变差时，容易被另一挡板更换或通过使用原位更换机构。为了确保喷嘴和能量束之间的正确对准，在相邻部件之间使用配合的轮廓表面。也可以使用螺纹表面来帮助实现适当的同轴对准。
