Electrodes “ UONI -13/55 ” designed for welding of high-duty constructions of carbon ( types: 08, 20, 20L, St 3) and low alloy steel (types 26GS, 09G2S), S235-S355, P235-P355, E295 (according to EN 10027-1, EN 10028-2, EN 10028-3). They are widely used to metal seams when placing increased demands on ductility and toughness even during working with low temperatures.

The chemical composition of metal:

Electrodes “ UONI -13/55 ” provide arc stability and forming of metal bead with high crystallization cracks resistance and low hydrogen content. Allow welding of especially high-duty metal constructions, operating with dynamic loading in low temperature conditions (to -40°С), and vessels that are working under pressure of shipbuilding steel structures. The more thickness’ metal welding and the welding of founding’s defects.
