Electrodes RS-48.18

Welding electrodes RS 48.18 are electrodes with the basic type of coating with iron powder, designed for welding carbon and low alloy steel.

The advantages of electrodes

The electrodes are characterized by high welding and technological properties. The iron powder content allows for a stable arc with minimal spatter. Easy slag removal.

High-quality seam with high Toughness at low temperatures (up to -30°C).

Increased plasticity. The deposited metal is resistant to cracking.

They can be used in all spatial positions.

Welding electrodes RS 48.18 by AWS A5. 1: E7018 /
comply with ISO 2560-A: E42 3 In 31 H5, GOST 9467-75: E50A, analogue ESAB OK-48.00


They are suitable for welding critical structures made of carbon and low alloy steels.

They are used in construction, shipbuilding, welding of pipes, boilers, pressure vessels


Welding can give off fumes and gases hazardous to health! Avoid inhaling these fumes and gases! Ensure proper ventilation! Special eye, body and respiratory protection must be used!

General guidance:

Calcination of welding electrodes before welding lasts for 1 hour at a temperature of 350°C.

The surface must be cleaned of rust, oil and other impurities before welding.

Welding must be done in a short arc.
