摘要： An electrode for a plasma arc cutting torch which minimizes the deposition of high emissivity material on the nozzle, reduces electrode wear, and improves cut quality. The electrode has a body having a first end, a second end in a spaced relationship relative to the first end, and an outer surface extending from the first end to the second end. The body has an end face disposed at the second end. The electrode also includes at least one passage extending from a first opening in the body to a second opening in the end face.

摘要： A plasma arc torch that includes a torch body having a nozzle mounted relative to a composite electrode in the body to define a plasma chamber. The torch body includes a plasma flow path for directing a plasma gas to the plasma chamber in which a plasma arc is formed. The nozzle includes a hollow, body portion and a substantially solid, head portion defining an exit orifice. The composite electrode can be made of a metallic material (e.g., silver) with high thermal conductivity in the forward portion electrode body adjacent the emitting surface, and the aft portion of the electrode body is made of a second low cost, metallic material with good thermal and electrical conductivity. This composite electrode configuration produces an electrode with reduced electrode wear or pitting comparable to a silver electrode, for a price comparable to that of a copper electrode.

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.
