Elimination of Electric Arc Stabilization in Precision Welding with High-Current DC Glow Discharge

摘要

The article considers the possibility of increasing stability of DC high-current glow discharge in the diffusion bonding processes at discharge currents 1 – 30 A and the gas pressure 1.33 – 13.3 kPa by replacing the monolithic anode with a multi-section one with the mobile anode sections. It is shown that the application of proposed devices which provides an increasing in the length of the inter-electrode gap to the values of 0.03 – 0.06 m during 10^-2 – 10^-1 sec is an effective way of extinguishing electric arcs arising from disturbing of the high-current glow discharge in welding and brazing.
