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. It is recommended to use electrodes for welding structures operated at low temperatures, when increased requirements for ductility and impact strength are imposed on the weld metal. 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 520 MPa; •impact strength (KCU + 20) – not less than 180 J/cm2 (KCV-20) – not less than 50 J/cm2 (KCU-60) – not less than 40 J/cm2
