Characteristics of an arc column in a hollow cathode arc

Welding International, 2006
Abstract The hollow cathode arc (HCA) was developed as a plasma source for low-pressure applications in the 1960s, since when it has been variously researched to clarify its underlying mechanism.1, 2 When arranged to incorporate a relatively high arc current, HCA can also be used as a welding heat source.3–5 Through being a plasma source in low ...

Characteristics of hollow cathode arc as welding heat source: Arc characteristics and melting properties

Science and Technology of Welding and Joining, 2002
A feasibility study has been conducted to determine whether a hollow cathode arc (HCA) can be used for a welding heat source in space, that is high vacuum and microgravity conditions. The HCA method enables the arc discharge to form under low pressure conditions by purging a small amount of gas through the centre of the hollow cathode.

AC arc characteristics

Russian Metallurgy (Metally), 2012
The dynamic and static current-voltage characteristics of the arcs in steel-melting furnaces are considered. The influence of the operation conditions of furnaces (arc current and length) on the currentvoltage characteristics is studied. An attempt of generalizing the controlling characteristics of furnaces with various capacities is made.

Further characteristics of the carbon arc

Electrical Engineering, 1937
In this paper the carbon arc is considered in its 3 characteristic forms, the low intensity arc, the high intensity arc, and the flame arc. The influence of arc current on the energy emission is discussed in relation to each of the 3 types, as well as the effects of variation in arc voltage.

Characteristics and uses of the carbon arc

Electrical Engineering, 1934
The high efficiency of the carbon arc, the flexible and uniform quality of radiation it provides, and its extremely high intrinsic brilliancy give it a prominent place in the broad field of illumination. For applications in which a powerful light must be obtained from a source of small dimensions, it is unsurpassed. Characteristics of the various types

Characteristics of Multichannel Arc Gap

Japanese Journal of Applied Physics, 2001
The characteristics of a multichannel arc gap are investigated experimentally in the voltage range of less than 45 kV using a ferrite sharpener. The gap comprises 12 or 24 steel needle electrodes and a brass rod electrode. We examined the characteristics of the number of arc channels when the following parameters were changed independently: (1 ...

Characteristics in reactive arc evaporation

Surface and Coatings Technology, 1997
Abstract Different cathode operation modes can be observed while sustaining the arc discharge in a reactive gas atmosphere (e.g., N2, CH4). The net consumption for both metallic and gaseous components can be analyzed by measuring cathode erosion rate and reactive gas flow.

Dispersion characteristics of arc-axis waveguides

Ultrasonics
Ultrasonic single mode excitation methods, mode separation algorithms and damage detection applications all require the calculation of the dispersion characteristics of the waveguide. However, existing dispersion calculation methods are mainly applicable to straight-axis waveguides.
