Product Description

AWS ECUSN-C aluminum bronze arc welding electrodes welding rods 
DESCRIPTION:

AWS ECuSn-C is one copper alloy electrode with tin and phosphor bronze as the core and low hydrogen flux coating. It has certain strength, good plasticity, impact resistance, wear resistance and corrosion resistance. The welding process has good performance and versatility. DC power supply and electrode are used to connect the positive electrode.

APPLICATION:

It is suitable for welding pure copper, brass, phosphor bronze and other kinds of metal. It can be widely used for surfacing welding of phosphor bronze bushing, ship propeller blade, etc. It can also be used for welding repair of cast iron and welding.

ATTENTION:

1. The electrode must be baked at 200"C for 1 hour before welding. Weld surface moisture, oil, oxide and other miscellaneous must be cleaned before welding.

2. The preheating temperature before welding is 150-250C for phosphor bronze, about 450"C for pure copper and about 200°C for carbon steel.

3. After welding, use flat head hammer to hammer the weld, refine the grain, eliminate stress, and improve the strength and plasticity of the weld.
