Аннотация: Powering the arc from a single-phase rectifier with a capacitor voltage multiplier and a choke coil inductance of 1.2 mH results in the formation of welded joints in welding with wires with a diameter of 0.8 and 1.2 mm with a current of 12 A or higher at straight polarity in CO2. At a current lower than 50 A, the melting factor incПоказать полностьюreases and the difference in the melting rates at straight polarity decreases in comparison with the melting rate at reversed polarity. According to films and oscillograms, the transfer of large droplets is accompanied by neither displacement of the droplets from the electrode axis nor by more intensive splashing. © 2015 Taylor & Francis.
