Energy parameters of weld formation process in MIG-MAG welding

The article presents results of an experimental study and simulation of the effect of welding arc energy characteristics on the nature of electrode metal transfer in MIG-MAG welding. Based on the research results, a method has been developed for determining the coefficient of welding arc plasma flow pressure. The method makes it possible to take into account the dependence of the electrode metal transfer pattern and plasma flow pressure on geometrical dimensions of a welded joint.
