A thin coated electrode intended for welding of Copper and Copper-Tin alloys.
CLASSIFICATION : AWS/SFA-5.6: E CuSn-C
CHARACTERISTICS :
A thin coated electrode intended for welding of copper and copper-tin alloys. Welding Suitable copper or Bronze to steels. For obtain best results, used short arc and control interpass temperature.
APPLICATION :
- Suitable for welding of Cast-Irons without preheat if machinability is not required.
- Also suitable for cladding
- welding suitable for Bushes, Brass parts, Valve seats, Bearing, ship propellers, Malleable Iron, Galvanized Iron, Impellers Blades,
RE-DRY CONDITION : Re-Dry the electrode at 150°C for 1 hour.
WELDING PRECAUTION :
- While welding copper or bronze, the work piece should be preheated to approx. 300°C.
- But in no case the working temperature should reach 400°C or above as this will result in hot shortness.
- When welding large jobs maintain the interpass temperature of 300°C.
