EXCEL BOND CU

TYPICAL APPLICATION

Electrical bus bar, Switch Gear, Transformer, Generator, Evaporator shell, Distillation columns, Cooling Pans, Heat Exchanger, Boiler, steam coils, High pressure conduits.

PRODUCT FEATURES

  1. Compatible with many copper alloys with excellent colour match.
  2. Deposits can be electroplated with Ni & Cr.
  3. Higher thermal & electrical conductivity of the weld.
  4. Suitable for Copper cladding of ferrous materials and for joining copper to steel.
  5. Excellent resistance to atmospheric & marine corrosion.

RECOMMENDATIONS

For arc welding applications requiring high purity copper deposit. Suitable for welding of all Copper grades.

PROCEDURE

Surface to be welded should be free from oxides, corrosion & all contamination. High thermal conductivity of Cu dissipates heat from the weld are rapidly, causing lack of fusion & porosity in the welds. It is therefore recommended to preheat large parts to 400-6000C. Use DC positive polarity for the electrode. Peen weld.
