A research about influence of wire electrode vibration’s amplitude upon process of arc-cycle conduction and forming of over- laid coating is done in a shield of argon. Duty cycle frequency, times of short circuit and arc burning as well as roughness of the coating are used as quality criteria. It is established that wire electrode vibration’s amplitude cause a significant influence as maximal value of arc cycles and lowest roughness of the coating are obtained at rate of 2 mm.

The influence of wire electrode vibration’s amplitude upon parameters of vibrating gas metal arc overlaying process in carbon dioxide shield. As main criteria for evaluation are chosen a voltage during periods of short-circuit and beginning of arc burning; welding current during period of short-circuit and its value at the end of arc burning. A significant influence of vibration’s amplitude upon parameters of the process was established as optimal values are shown at rate of 0,5 mm.
