Calculation of optimal parameters of vibration electrode for are welding

Abstract

Manual and semi-automatic welding by vibration electrode (pulsing are) is considered in the article. The advantages of welding by the pulsing arc are determined in comparison with welding by a constant arc. Using energy calculation by taking into account thermal balance at the vibration electrode stub, optimal parameters of modulated current, such as frequency and duration of electrical pulses, were established for different welding methods and regimes. Stabilized heat that is required for generating melting drops reduces the level of metal splash and improves formation of the weld.
