ERCuSi-A Welding Wire (CHM-Cu6560)

ERCuSi-A is a kind of silicon bronze MIG wire and it is used for welding silicon bronze, red copper, brass and aluminium bronze, also it is used for dissimilar metal surfacing of copper with cast iron or copper with steel, as well as for brazing galvanized steel sheet, such as brazing doorframes of motor vehicles and motorcycle parts, surfacing rubbing surface of locomotives & carriages and heavy machineries. The melting copper has good flowability and its weld metal has good mechanical properties, good corrosion resistance and good abrasive resistance.

Welding Position: F, HF, V

Type of Current: DCEP

Notice:

  • Keeping the package of the wire in good condition before welding.
  • Both the surfaces to be welded of weldment and wire must be cleaned away impurities of oil contamination,rust, oxide coating, moisture and so on.
  • It is better to put a subplate under the weld zone to prop the melted metal so that to ensure complete penetration the weldment.
  • The welding conditions mentioned above for reference only and it is better to do a welding procedure qualification according to project before put it into formal welding.
