Spectral Characteristics of High Current Hollow Cathode VacuumArc

On the condition of 100 A welding current the frequency of optical emission from argon plasma in a hollow cathode has been recorded as 200~1 000 nm with water cooled copper anode. Spatial distribution (along the arc length) of hollow cathode vacuum arc spectrum is also given. The observed spectra shows that strong Ar Ⅰ and Ar Ⅱ lines are superimposed on a weak continuum. Large amounts of Ar Ⅱ spectral lines apppear in the region of 350~510 nm,which results in a blue hollow cathode vacuum arc. All the results indicate that the spectral line can be used to analyze the mass and energy transfer in hollow cathode vacuum arc welding plasma arc.
