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

Application:

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

Attention:

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.
