Information × Registration Number 0207U000023, 0102U003954 , R & D reports Title Investigation of mechanism of weld-adjacent cracking at arc welding of structure cast irons with increased strength ( ?в до 400 МPа). popup.stage_title Head Gretskyy Yuriy, Registration Date 03-01-2007 Organization E.O.Paton Electric Welding Institute of the National of Sciences of Ukraine popup.description2 On the base of studying of physico-metallurgical peculiarities of structure cast iron welded joint formation, influence of physical and chemical inhomogeneity on process in fusion and heat affected zones, the insight as to nature and mechanism formation of hear-weld cracks has been developed. The scientifically grounded complex of metallurgical and technological measures for cracking prevention has been created. The technology of the arc welding without preheating and postweld treatment for rebuilding of massive cast iron parts of ship internal-combustion engines has been designed and reduced to practice. The technological documents and technological process have been approved by Shipping Register of Ukraine. Product Description popup.authors popup.nrat_date 2020-04-02 Close
