Silver-containing Copper alloy for welding deoxidized copper. The molten pool is clean. The deposit is tough and free from porosity. Because of about 1% silver, the molten metal has better fluidity and wetting properties.
Deoxidized copper welding rod used for joining and surfacing of copper. Used in chemical, food, paper, textile, brewery, and shipbuilding industries. Suitable for furnace brazing of steels.

Acetylene torch, neutral flame. TIG/MIG processes.
Prepare V-groove of about 60°C where the thickness is more than 5mm. Clean the joint thoroughly. Apply flux on the joint area. Use neutral flame. Preheat a broad area, then heat locally until flux melts. Apply the flux to the rod by dipping heated end into the flux and melt the rod into the joint.
Remove flux residues mechanically or chemically (using 10% sulphuric acid) followed by rinsing in running water.
