“Electrodes UONI-13/55 characterized by stable arc burning, forming metal seam with high resistance to crystallization cracks formation and hydrogen content no more than 10 cm3 / 100 g. Electrodes are suitable for welding critical structures, which operate under dynamic load at low temperatures (up to -40 ° С), pressure vessels. Widely used in shipbuilding and tanks construction. It is possible to weld metal of a large thickness, surfacing details of agricultural machinery, rewelding of casting defects.

PURPOSE AND FIELD OF APPLICATION

“UONI-13/55” electrodes designed for welding of critical structures made of carbon steel (such as 08, 20, 20Л, Ст3) and low alloy steel (such as 16ГС, 09Г2С) and steels S235-S355, P235-P355, E295 (according to EN 10027-1, EN 10028-2, EN 10028-3). Applied when the metal stitches are subject to increased requirements for plasticity and impact strength, in particular, when working at low temperatures.

APPLICATION CONDITIONS

Welding is performed on DC of reverse polarity, in all spatial positions except the vertical down. Welding is carried out with a short arc or support on the cleaned edges of the seam with a direct current of reverse polarity. Voltage on arc is 23-27 V. Electrodes UONI-13/55 are sensitive to porosity in the case of rust and grease on the edges of welded parts, or when arc elongation takes place.

REDRYING BEFORE WELDING

At the normal storage conditions, redrying is not required. In case of moisture, the redrying is made at 300±350°С for 1 hr. Moisture content in the coating should not exceed 0,3%.
