- spatter and burning losses of metal are compensated;
- electrode consumption reduced by 10-15%.
- deposition rate increased by 8-10 %.
- slag does not flow into the molten pool, forming smooth weld seam thereby slag can be easily removed.
PURPOSE AND FIELD OF APPLICATION
Electrodes “УОНИ-13/55 Plasma” Designed for welding in all the spatial positions, except vertical down, of critical structures and pipelines made of carbon and low alloy steel with tensile strength from 500 MPa to 640 MPa, especially if hot cracks resistance of welding joints is needed. Are widely used in bridge building, shipbuilding, ship repairing and tanks production.
APPLICATION CONDITIONS
Deposition rate factor – 10,5-11,5 g/А.hr. Electrode consumption per 1 kg of deposited metal is 1,58 kg. Nominal capacity up to 115%. Electrodes from 2 mm to 4 mm diameter designed for welding in all spatial positions except vertical down, 5 mm diameter electrodes – for horizontal flat, vertical flat, and vertical up positions.
REDRYING BEFORE WELDING
At the normal storage conditions, redrying is not required. In case of moisture redrying is made at 380-420°С for 60 min. Moisture content in the coating should not exceed 0,3%.
