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.
Chemical Composition (%):
C (0.06-0.15) Mn (1.40-1.85) Si(0.80-1.15)

CO2 FLUX CORED WIRES
MT-FC71T-1 is of oxide of titanium type slagkind CO₂fluxcored wires for all positions welding inclusive of vertical down. The arc isstable with little spatter. The welds have smooth appearance. The slag is easyto remove and smoke little. It has excellent welding technologicalperformances.
For welding Iow carbon steel and 50kg/m㎡ class high tensile steel. It is widely usedfor welding structures of ships，bridges， buildings， storedtanks and steel beams etc.
Note on usage:
1.Strictly control the content of impuritiesin CO₂， guarantee the purity of CO₂
2.The flow of CO₂is normally 20-251/min， when welding.
3.The outer length of wire should becontrolled within 15-25mm.
