DAMPING OF WELDING CURRENT FLUCTUATIONS IN ROBOTIC ARC WELDING

G.A. TSYBULKIN

E.O. Paton Electric Welding Institute, NASU, Kiev, Ukraine
 
 
Abstract
The possibility of damping undesirable current fluctuations in welding circuit was considered. A criterion was derived which allows assessment of damping properties of welding circuit directly by its parameters.
 
 
Keywords: robotic arc welding, consumable electrode, stability of process, aperiodic modes, damping of welding current fluctuations
