PROPERTIES:
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.
APPLICATIONS:
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.
TECHNICAL DATA:
| UTS of joint Mpa | Elongation%(L=4d) | Working temperature |
| 170 min | 20 min | 1060°C |
HEAT SOURCES:
Acetylene torch, neutral flame. TIG/MIG processes.
PROCEDURE:
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.
CLEANING:
Remove flux residues mechanically or chemically (using 10% sulphuric acid) followed by rinsing in running water.
