GMAW full-strength copper-coated wire with de-oxidizing additives Mn and Si. This product is designed for welding with semiautomatic welding followed by gas protection C1 (CO2) or a mixture of M21 (Ar + CO2). The increased Mn content provides greater weld strength, greater surface resistance and greater impact resistance than the IMT2E wire. Working temperature of welding joints -20 ° C to 350 ° C. The IMT3 should be used for work with unrefined structural steels, boiler steels, ship structural steels and low-alloyed, C-Mn high-strength steels.
