CAST BRONZE (AWS A5.6: ECuSn-C)

Product Specification

A thin coated electrode intended for welding of Copper and Copper-Tin alloys.

 CLASSIFICATION : AWS/SFA-5.6: E CuSn-C

 APPROVAL         :

 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               :

 1) Suitable for welding of Cast-Irons without preheat if machinability is not required.

2)  Also suitable for cladding,

3) 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 TECHNIQUES:

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.
