Information × Registration Number 0207U000016, 0105U001727 , R & D reports Title Investigation of structural-phase characteristics and means of assurance of highly-tough state of metal of welded joints of gas-oil pipe with preset service properties in arc welding. popup.stage_title Head Rybakov Anatoly Aleksandrovich, Кандидат технічних наук Registration Date 03-01-2007 Organization E.O.Paton Electric Welding Institute NAS of Ukraine popup.description2 Structural-phase characteristics of weld metal of microalloyed pipe steel, guaranteeing its high service characteristics, are defined. Technological means of achievement of high-tough state of metal of pipe welded joints have been developed such as: optimum composition of agglomerated flux was defined for multi-arc welding of pipes, composition of flux-cored wire was developed for 2-, 3- and 4-arc welding of pipes, guaranteeing the microalloying of welds with titanium and boron, process of multi-arc welding of pipes was developed using this flux-cored wire on one of the arcs.
