KAWAT LAS TEMBAGA E-Cu SMAW / STICK NIHONWELD N-CU39 (harga per box)

AWS : A5.6 E Cu
Length : 350mm
Packing Price : 5kg/box
Diameter : 2.5 mm / 3.2 mm

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
