KAWAT LAS TEMBAGA E-Cu SMAW / STICK NIHONWELD N-CU39

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
