Welding electrodes UONI 13/55 Plasma E7018-1

AWS A5.1: E7018-1 H8

EN ISO 2560-А-E 46 5 В 3 2 Н5

Welding electrodes UONI 13/55 Plasma E7018-1

designed for welding in all spatial positions, except vertical down one, of critical structures and pipelines made of carbon and low-alloy steels
with a tensile strength of 530 MPa to 680 MPa, especially if it is necessary to ensure high resistance of welded joints to cold cracks

Special properties

they are characterized by high strength of the weld metal, with special metallurgical purity and low hydrogen content in the deposited metal
the possibility of alternating current welding eliminates the effect of magnetic arc blow
stable electrode metal transfer during welding ensures improved
weld joints formation
the slag does not flow into the welding bath, an even seam is formed,
and the resulting slag crust is easy to remove
deposition rate factor: 0,18 – 0,20 g/А·min
consumption of electrodes per 1 kg of deposited metal: 1,4 – 1,6 kg

UONI 13/55 Plasma Е7018-1 electrodes are designed for critical structures welding made of carbon and low-alloy steels with an increased yield strength, operating under alternating loads at low temperatures of up to -50 ˚С. They are widely used in bridge construction, shipbuilding as well as pressure vessels production.
