Welding electrodes Monolith RB

AWS A5.1:Е6013

EN ISO 2560-A: E 42 2 RB 1 2

electrodes with a diameter of 2.5 mm to 4 mm are suitable for welding in all spatial positions except vertical down one.

Special properties

offer easy striking and restriking characteristics
provide soft and stable arc burning, low spatter loss, easy separation of the slag crust, excellent weld metal formation
are used for welding with both direct and alternating current of sheet steels and steel constructions that are working under steady and dynamical loads, as well as for welding of reservoirs and pipelines where high mechanical properties of the weld should be provided
deposition rate factor: 0,13 – 0,14 g/А·min
consumption of electrodes per 1 kg of deposited metal: 1,6 – 1,7 kg

Electrodes are designed for welding of structures and reservoirs, as well as pipes and pipelines. They are suitable for root welding and welding of non-rotating pipe joints made of constructional steels with yield strength of up to 500 MPa as well as steels of P235/S235 - P355/S355 and similar grades.

WEDGE METAL MECHANICAL PROPERTIES

According to AWS A5.1 / Typical Results

Tensile strength, MPa ≥ 500
Yield strength, MPa ≥ 20

Baking before welding

permissible moisture content in the coating before use is not more than 0.3%
in case of electrode coating wetting above the norm - dry for 60 minutes at 250±10 °С

Welding modes

Welding current strength, A for electrodes with a diameter of, mm
