Bronze Welding Wire ERCuSn-A
Bronze Welding Wire ERCuSn-A
AWS ERCuSn-A is a tin bronze welding wire containing about 6% tin and about 0.15% phosphorus.
Phosphorus is used for deoxidation.
Because it contains tin, the molten metal has good fluidity.
The alloy is mainly characterized by high strength, wear resistance and corrosion resistance.
APPLICATION: Suitable for the welding of copper, such as copper and copper-tin alloy, especially for the connection welding of brass and steel.
It is very suitable for repair welding of copper castings.
Preheating is required for large area TIG welding, and pulse arc welding or furnace welding is used for surfacing of steel.
It is used for argon arc welding of copper base alloy and brazing of steel.

Instructions:
1. Before welding, the oxide film and oil stain on the welding edge of the workpiece shall be strictly removed; otherwise the weld will be melted Poor sealing will cause defects such as pores and slag inclusion.
2. In order to ensure the penetration of welding without collapse, a cushion can be used to hold the molten metal during welding.
3. During the welding process, in order to prevent the adverse effects of Sn evaporation and oxidation on the welding process,
Small linear energy welding is recommended.
RFQ:
1.What is the welding melting point for AWS ERCUSN-A?
The welding melting point is 1025℃
2.What is the gas used for the bronze welding ?
The gas used for the bronze welding is Argon
3. Can the welding bronze rod be used for bronze to stainless steel ?
The welding bronze to stainless steel is not recommended , due to the different reatction temperatures and coefficients of therman expansion
between the two metals. This can cause wrapping ,cracking, and other issues. Copper-based brazing rods are a better choice for joining the two
metals
