Cu107
[Copper 107] Red Copper welding rodin line with GB ECu, equivalent to AWS ECu
Description: Cul07 is a pure copper electrode with pure copper as the core and low-chlorine coating. It has good mechanical properties and good corrosion resistance to the atmosphere and sea water. It is not suitable to weld oxygen-containing copper and electrolytic copper. With DC power supply, the electrode is connected to the anode, the arc is stable and the shape is good.
Uses: Mainly used for welding conductive copper bars, copper heat exchangers, seawater pipes for ships and other copper structural parts. It can also be used for surfacing welding of seawater-resistant carbon steel parts.

Chemical composition of deposited metal (%)

Precautions:
1. The electrode must be baked at about 200°C for 1 hour before welding. Impurities such as moisture, oil stains and oxides on the surface of the weldment must be removed before welding.
2. Under normal circumstances, the preheating temperature should be controlled between 400-500'C. Short arcs should be used when welding, and reciprocating linear motion should be used to improve the shape of the weld.
3. For longer welds, the gradual back welding method should be used, and the welding speed should be as fast as possible. During multi-layer welding, the slag between the layers must be completely removed. After welding, hammer the weld with a flat-head hammer to eliminate stress and improve the quality of the weld.
