Electrodes for welding high-alloy steels OZL-17U

THE MAIN PURPOSE OF. Electrodes with rutile-basic coating for welding of important equipment made of corrosion-resistant alloy 06HN28MDT, 03KHN28MDT and steel grade 03KH21N21M4GB mainly in thickness up to 12 mm. working in mediums of sulfuric and phosphoric acids with additives of fluorides. Welding in all spatial positions with direct current of reverse polarity. NTD GOST 9466-75, THE 14-4-715-75 TECHNOLOGICAL FEATURES. The rod of wire brand SV-01Х23Н28М3Д3Т GOST 2246-70. The diameter of the produced electrodes are 3.0 and 4.0 mm. CHARACTERISTICS OF MELTING OF THE ELECTRODES. Performance (for diameter 4.0 mm) 14.0 g/(A x h):2.0 kg/h. electrode Consumption per 1 kg of weld metal-1.7 kg. THE SPECIAL PROPERTIES.The weld metal is characterized by high corrosion resistance and resistance intergranular corrosion when tested according to the methods In GOST and WU 6032-89. TECHNOLOGICAL FEATURES OF WELDING.Welding metal thickness up to 12 mm, it is recommended to produce cushions with full width cutting, welding of metal of greater thickness, with double-sided groove. When welding critical structures is necessary to remove the craters by grinding. THE SYMBOL ELECTROTOOL-17U-Ø-VD GOST 9466-75 E-400-БР20 THAT 14-4-715-75
