摘要： Some embodiments herein are directed to devices and methods for automatically starting a plasma utilizing a wand. In some embodiments, the wand may be used to start a plasma in a plasma torch such as, for example, a microwave plasma torch or an induction plasma torch, as discussed below. The wand may comprise an elongate, hollow wand member comprising a closed distal end, a proximal end, and one or more apertures extending from a hollow interior of the wand member to an exterior surface of the wand member; and an elongate wire member positioned within the hollow interior of the wand member and extending along at least a portion of a length of the wand member, wherein the wire member is configured to be placed in operable communication through the aperture with a power source, such that the power source can be activated to in turn start the plasma within the plasma torch. The plasma torches discussed herein may be used in various applications including, for example, high volume synthesis of advanced materials such as nano-materials, micro-powders, coatings, alloy compositions for additive manufacturing.

摘要： A computerized method is provided for automatically determining at least one characteristic of a workpiece for processing by a plasma arc processing system. The method includes electrically connecting the workpiece to the plasma arc processing system that includes a plasma arc torch. A distal tip of the plasma arc torch is configurable to be positioned proximate to the workpiece. The method includes supplying, by the plasma arc processing system, an electrical current with a low amperage to the workpiece, the low amperage current insufficient to cut the workpiece, and monitoring, by the plasma arc processing system, a path of the electrical current relative to the workpiece. The method further includes determining, by the plasma arc processing system, the at least one characteristic of the workpiece based on the electrical current path monitored.

摘要： A 3D-cutter and a method for controlling a 3D-cutter are disclosed. The 3D-cutter includes a tiltable torch which is able to produce a cutting beam and a conveyor having a conveyor support surface with gap extending in Y-direction. The tiltable torch is moveable in both X-direction and Y-direction as well as Z-direction. Conventionally, the X-position of the entrance point or exit point of the beam in the sheet blank is kept constant relative to the gap, namely centrally between the upstream and the downstream gap edges and the sheet blank is moved back and forth in X-direction by the conveyor to form 3-dimensionally shaped bevel cuts. The X-position of the entrance point or exit point of the beam in the sheet blank may be varied relative to the gap. Thus, smaller workpieces may be produced.

摘要： Various embodiments may be generally directed to a welding system that monitors an output of the welding system to determine if an output arc should be extinguished or maintained. The welding system can compare an arc voltage output to a voltage threshold and a temporal threshold. When the arc voltage output exceeds the voltage threshold in an uninterrupted manner for the duration of the temporal threshold, an output weld current can be stopped. In turn, the output arc can be broken or extinguished. After a predetermined amount of time, the power source can be re-engaged to prepare for re-ignition of another arc. By tracking the amount of time the arc voltage output exceeds the predetermined threshold, a probability of unwanted arc outs can be reduced or minimized while still providing quick and reliable arc breaking when desired.

摘要： A computer numerically controlled machine may include a movable head configured to deliver electromagnetic energy to a part of a working area in which the movable head may be commanded to cause delivery of the electromagnetic energy. The interior space may be defined by a housing and may include an openable barrier that attenuates transmission of light between the interior space and an exterior of the computer numerically controlled machine when the openable barrier is in a closed position. The computer numerically controlled machine may include an interlock that prevents emission of the electromagnetic energy when detecting that the openable barrier is not in the closed position. The commanding may result in the computer numerically controlled machine executing operations of a motion plan for causing movement of the movable head to deliver the electromagnetic energy to effect a change in a material at least partially contained within the interior space.

摘要： A method for cutting side plates and end plates of a scrapped railway boxcar aims to improve low disassembling efficiency as it is difficult to disassemble the scrapped railway boxcar. The steps of cutting the side plates includes: A1: cutting a top of an upper side plate; A2: performing cutting downwards, dividing the upper side plate, and then cutting the left upper side plate; A3: cutting the right upper side plate; A4: cutting a lower side plate; A5: cutting off upper channel steel on columns; A6: cutting off lower channel steel on the columns; and A7: cutting the columns. The method avoids complicated working conditions of directly cutting angle iron, the channel steel, multilayer boards and closed regions, so that the cutting efficiency of the side plates and the end plates of the boxcars is improved. Moreover, automatic cutting can be realized according to a set cutting path.
