CO2 GAS-SHIELDED WELDING WIRE
MT-C56 is Iow alloy steel type wires covered with copper. It is able to prevent gas porosity and slag inclusion producing due to the deoxidation depending on Mn and Si in the wire jointly. In this way， the crack resistance of weld metal can be
developed and obtained satisfactory mechanical properties.
For welding mild steel and 500Mpa grade of high strength steel structures， such as ships， vehicles， bridges and etc.
