Information × Registration Number 0207U000018, 0106U000090 , R & D reports Title To investigate influence of the form of a variable polar and unipolar current on parameters of welding by an melted electrode in protective gases. popup.stage_title Head Andreev Viatcheslav Valentinovich, Registration Date 03-01-2007 Organization E.O.Paton Electric Welding Institute of the National of Sciences of Ukraine popup.description2 Experimental researches of influence of the form alternating and a unipolar current on parameters of welding in protective gases. The power supply of a variable rectangular current which will consist of the transformer, throttle, thyristor a regulator and the block of management is developed and made. The device for management of the form of a pulse of a current is developed. At welding in protective gases positive results are received at a feed{meal} of an arch by a variable rectangular current and a pulse current at welding by a powder wire.
