1. A control circuit in plasma arc cutting and welding equipment designed for transferred arc operation, comprising: a torch having a fixed electrode, and a movable nozzle capable of shifting axially in relation to the electrode between a transitory position, in which said electrode and said noz...
Although the machining process using five-axis NC machines makes it possible to achieve the desired complex shape [2], it is only effective for the unitary helix integral impeller at present and ineffective for the double one. Furthermore, the five-axis NC machine-based process requires the ...
Another interesting configuration of a microwave plasma torch [50] combines arc and microwave discharges to enhance the size and enthalpy of the plasma torch. The hardware involves cylindrical-shaped plasma torch module is integrated into a tapered rectangular cavity to form a microwave adaptor. The ...
Wire arc additive manufacturing (WAAM) has been investigated to deposit large-scale metal parts due to its high deposition efficiency and low material cost. However, in the process of automatically manufacturing the high-quality metal parts by WAAM, several problems about the heat build-up, the d...
Thus, when the base microstructure must bepresented also in the cutting regions, this wide layer mustbe removed, often by costly machining operations.Improvements achieved by the development of high toler-ance plasma arc cutting (HTPAC) process suggest its appli-cation to titanium alloys. In the...

(DC) voltage regulation to pulses in the unipolar-polarisation voltage led to a substantial increase in the average current density during the process, which theoretically corresponds to an increased material removal rate. This is the basic principle of PUP-PEP. In this process, the machining ...
