CO2 gas shielding welding wires

CO2gas shielding welding wireshave excellent mechanical performance such as fast melting rate, high depositing efficiency, stable arc, little spatter, beautiful seam. Suitable for all-position welding work.
   The series of welding wries can be used to welding low carbon steel and low alloyed steel structure, such as ships, vehicles, bridges, boilers and buildings construction machine,rail way construction,
This series of welding wires has different kinds of packing,such as different types of Plastic spools,metal spools and straightened wire in plastic tube.
