TYPICAL 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.
HEAT SOURCES : Acetylene torch, neutral flame. TIG/MIG processes.
PROCEDURES
Prepare V-groove of about 600 where 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 in to the joint.
CLEANING
Remove flux residues mechanically or chemically (using 10% sulphuric acid) followed by rinsing in
running water.
