INVESTIGATION OF THE ARC PROCESS OF A SPLIT ELECTRODE IN A GAS METALL ARC WELDING

Based on the experimental data, the influence of the voltage of the power source on the nature of the existence of the arc and droplet transfer of the electrode metal during surfacing by a split electrode in a protective carbon dioxide and argon gas mixture is revealed. The voltage ranges for the main types of arcs on a split electrode are determined, the causes and mechanisms of the formation of these types are described.

INVESTIGATION OF THE ELECTRODE DESIGN OF A SINGLE-MODE PIEZOELECTRIC ACTUATOR

This study investigated the electrode design and output performance of a single-mode piezoelectric actuator. The relevance between the design parameters of the electrode and the vibration amplitude of the friction element was determined. Two split electrode design methods, horizontal and vertical, were investigated. The Taguchi method was used to investigate the relevance of the exciter electrodes and the vibration amplitude of the piezoelectric actuator. The simulation experiments demonstrated that the vertical split electrode design can be used to adjust the Y vibration amplitude. The thrust force measurement demonstrated that the thrust force of the piezoelectric actuator can be adjusted by using the split electrode design.
