Description
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).Metallurgical properties of wires provide high-quality welds and reliable wire feed in the mechanised welding process. Working temperature of welded joints from (-40°C up to 450°C). IMT 2 is intended for welding non-alloy structural, boiler, shipbuilding and low-alloy C – Mn steels with increased strength.
