Basic-type electrodes are designed for manual arc welding of critical structures made of carbon and low alloy steels in all spatial positions, except for vertical-downward welding. The electrodes are characterized by a low content of diffusion-mobile hydrogen, as well as sulfur and phosphorus, with an optimal content of alloying components, which makes it possible to obtain a high-quality welded seam. High indicators of mechanical properties ensure reliability and durability of welded structures, even at operating temperatures below -60°C. Certificates for UONI 13/55 electrodes: •GOST-R Certificate of Conformity; •NAKS Certificate; •Certificate of the Russian River Register; •Certificate of the Russian Maritime Register of Shipping. Mechanical properties: •ultimate strength – not less than 530 MPa; •impact strength (KCU + 20) – not less than 190 J/cm2 (KCV-20) – not less than 50 J/cm2 (KCU-60) – not less than 40 J/cm2
