dcterms:description
Electric arc produced by cutting plasma torch was observed by CCD camera. Fluctuations in arc plasma intensity were examined in several frequency intervals up to 50 kHz and distributions of their intensities were compared. Plasma torch was operated repeatedly in fixed-time cycles resulting in progressive wear of cathode and nozzle. Changes in distribution of overall arc intensity are rather small, showing compression and expansion zones. However, distributions of fluctuations intensities differ significantly during the nozzle lifecycle, exhibiting formation of double-layer structure and other noticeable changes. The fluctuation distributions are also influenced by frequency interval chosen for the analysis. Electric arc produced by cutting plasma torch was observed by CCD camera.
