The Management of Short Circuits' Mechanism of CO2 Shielded Welding

[摘要] It is observed the mechanism of short circuits' management in the process of which drops of electrode material move to welding pool and all the phases of drops' formation process are under control. It is shown the role of drop of electrode material and welding pool in the decreasing arc space, providing forced short circuit of arc space at the time of sharp decrease of welding current. Obtained results evidence that it is necessary to consider the movement of welding pool at the time of creation of model of electrode materials movement and creation of process management's algorithms, especially considering changeable position of welding pool, as the role of drop and welding pool in the decreasing arc space is almost the same.
