AWS : A5.6 E Cu

Length : 350mm

Packing Price : 5kg/pack

Description:

- N-Cu is a special electrode used for welding pure copper

- Designed for use without preheating and shows deep penetration

- Produces high purity copper weld deposits

- Corrosion resistant

- Excellent electrical conductivity

- Perfect color to match with copper

Application:

- Welding of pure copper

- Suitable for repairing welding of the parts that requires electric conductivity, such as repairing welding

of electrode holder, flange, etc

- Commonly used to overlay steel or to join heavier sections of copper to steel

Remarks :

- Preheat thicker sections to 400-600ºC

- Use a larger electrode for thicker sections and maintain a short arc

- Stress and distortion can be avoided by peening each deposit between passes

- Allow the part to cool slowly before removing slag with a chipping hammer and wire brush
