Description

【Quality Material】：The package includes 10 PCS 16”length flat copper brazing rods，BCuP-2 phosphor copper welding rod composition : Phosphor (P): 7%, Copper (Cu): the remainder .No flux required for soldering copper pipes. Flux must be added when copper and iron pipes are welded. 【𝐆𝐨𝐨𝐝 𝐋𝐢𝐪𝐮𝐢𝐝𝐢𝐭𝐲】：Copper solder Low metling point 640-770℃. Solidus: 1310°F, Liquidus: 1490°F. Tensile Strength ( RM): 838 MPa. The PhosCopper brazing rods has 𝐆𝐨𝐨𝐝 𝐋𝐢𝐪𝐮𝐢𝐝𝐢𝐭𝐲 during welding, strong caulking, and can flow into small spaces.Phosphor Copper brazing rods have a lower melting point than other brazing rods. 【Application Widely】： Brazing rods for copper hvac is used for brazing of copper & copper alloy in motors, air-conditioners, meters, and refrigeration industry.Also can braze some pipes,wire or the small copper braze job and the art project . 【Packaging】： GEOYLE welding rod packaging is packaged in a sealed tube, come in a fairly standard housing, with the rubber caps on the ends. can long-term storage,The rubber caps do not come off easily prevent sprinkle down ​of phosphor bronze welding rods. 【Service】： When you have a problem during the use of the electrode, please contact us immediately, we have professional welding engineers to solve the problem for you. Looking forward to your suggestions for welding rods, we will continue to improve our products and serve you better. Product name: Phosphor copper welding rod BCu93P

Welding method
1. Clean or expand the surface of the pipe fittings to be welded. The expanded pipe should be smooth, round, free of burrs and cracks, and uniform in thickness. Use sandpaper to polish the pipe joint to be welded, and finally wipe it clean with a dry cloth.. Otherwise, the solder flow and welding quality will be affected.
2. Insert the copper pipes to be welded overlapping each other (pay attention to the size) and align the centers of the circles.
3. When welding, the parts to be welded must be preheated. Heat the pipe welding joint with a flame. When the copper pipe is heated to purple-red, remove the flame and place the solder at the mouth, so that the solder melts and flows into the welded steel parts. The temperature after heating can be reflected by the color.

Precautions:
1. Before brazing, grease, oxides and other contaminants must be strictly removed from the brazing joint and the solder surface.
2. No brazing solvent is required when brazing copper, but silver flux should be used when brazing copper alloys.
