Thin Coated Electrode for Welding of Copper and Copper-Tin Alloys
Classification:
- AWS/SFA-5.6: E CuSn-C
Characteristics:
A thin coated electrode designed for welding copper and copper-tin alloys. Suitable for welding copper or bronze to steels. For best results, use a short arc and control interpass temperature.
Applications:
- Welding cast iron without preheating if machinability is not required.
- Cladding applications.
- Welding bushes, brass parts, valve seats, bearings, ship propellers, malleable iron, galvanized iron, and impeller blades.
Re-Dry Condition:
Re-dry the electrode at 150°C for 1 hour before use.
Welding Precaution:
- Preheat the workpiece to approximately 300°C when welding copper or bronze.
- Do not allow the working temperature to exceed 400°C to avoid hot shortness.
- For large jobs, maintain an interpass temperature of 300°C.
