Abstract
The forms of hydrogen existence in welding fused flux AN-348A were examined using the methods of IR-spectroscopy, thermogravimetry and gas chromatography. As model substances the zeolite NaA and kaolin were used. A significant difference of flux AN-348A from the zeolite is shown by a nature of a thermal hydrogen desorption. It is established that the main part of the latter is dissolved in the flux examined during the process of furnace melting in the form of a hydroxyl and removed at heating above 800 ^oC.
Keywords: hydrogen, water, hydroxyl, fused flux, zeolite, kaolin, thermal desorption
