Opis
An electrode wire, copper-covered, with an addition of deoxidizers Mn and Si for semi-automatic welding in the shielding C1 (CO2) and mixture shielding M21 (Ar + CO2). Increased Mn content provides higher weld strength, higher weld resistance to weld surface contamination and better impact strength. Working temperature of welded joints from (-40°C up to 350°C). IMT 3E is intended for welding non-alloy structural, boiler, shipbuilding and low-alloy C – Mn steels with increased strength for general application.
