Abstract: The invention relates to automatic welding, namely automatic welding non-consumable electrode wire \ with the addition of inert gases, mainly to the orbital welding joints of pipes sunk, which is used in the installation and repair of energy facilities, petrochemical complex, shipbuilding and aerospace industry, energy and chemical engineering and other industries, including the installation, repair and renovation of nuclear power equipment. Method multipass automatic welding of non-consumable electrode serving \ wire, followed by welding of filling and facing seams joints from opening edges engaged with fluctuations in non-consumable electrode across the seam, in which before performing the next weld determine this seam distance between the edges of opening the junction and the results of determination are non-consumable electrode oscillation parameters, namely the coordinates longitudinal axis of each passage in this respect seam edges with a joint of disclosure; vibration amplitude non-consumable electrode relative to the longitudinal axis of each aisle adjacent to the junction edges disclosure and non-consumable electrode oscillation amplitude relative to the longitudinal axis for all other passes. Found parameters used to program the controller and drive cycle welding kolyvacha non-consumable electrode device for multipass welding of non-consumable electrode automatically adding \ wire. Device for implementing the method multipass automatic welding of non-consumable electrode with the addition \ wire that contains, among other things, automatic welding with non-consumable electrode controller cycle welding mechanism transverse movement of the torch from the non-consumable electrode executive motor and encoder to the controller over kolyvacha non-consumable electrode auxiliary power supply with sensor test current and Computer-software device into a digital block comprising at least a processor node information storage and data bus, the main objective of which is to determine, in an array of data coming from the encoder and sensor test current distance between edges disclosure junction and, as a result of the determination, calculation and transmission of the relevant controller cycle welding and about kolyvacha non-consumable electrode control signals that are proportional to the coordinates of the longitudinal axis of each passage in this seam relative to one of the edges of opening the junction, the oscillation amplitude non-consumable electrode relative to the longitudinal axis each aisle adjacent to the junction edges disclosure and non-consumable electrode oscillation amplitude relative to the longitudinal axis for all other passageways to control the movement of non-consumable electrode burner prystoroyu for multipass welding of non-consumable electrode automatically adding wire. The invention provides expansion of technological capabilities and quality welds with multipass automatic TIG-welding with non-consumable electrode fluctuation and serving \ wire.
