Algorithms for controlling inverter sources of welding current to optimize the electrode metal transfer parameters

Methods and technical solutions directed at improving the welding process with short-circuiting of the arc gap, implemented on the basis of development of special algorithms for controlling the operation of inverter sources of welding current, are described. It is shown that both the partial control of the individual phases of short-circuiting and complete control solve to a certain extent the problems of energy and resource saving, control of the shape of the welded joint and the quality of welding operations.
