Abstract

The research was carried out on a vibrating arc device for welding in shielding gases "ENTON-60" with an axisless inertial vibrator. The following criteria were used to evaluate the progress of the electric arc process and the formation of the vibro-welded coatings: short-circuit voltage, voltage at the beginning of arc burning, magnitude of the short-circuit current and magnitude of the current at the end of arc burn-ing. It has been established that the vibration amplitude has a significant effect on the vibro-arc process, as the minimum magnitude of the short-circuit current and the lowest voltage at the beginning of arc burning occurs at a vibration amplitude of 1 mm when welding with the low-carbon wire Sv 08G2С of cast iron in CO2.

Keywords

Vibrating arc welding in CO2, vibration amplitude, electrical parameters
