If no... Please review the following papers on aluminum soldering: Direct Aluminum Solder Paste (IMAP Thermal Management Workshop – Palo Alto, CA, 2011) Soldering Aluminum (SME International Brazing & Soldering Conference – Orlando, FL, 2009). In the case of aluminum, most brazing material melts around 800-900 degrees, which is still a few hundred degrees short of aluminum’s melting point. Flux It. Preheat both the copper and aluminum tubing, focusing the heat slightly more on the copper than the aluminum (since copper has a higher melting point than aluminum) Dip the soldering rod into the Super Alloy 1 liquid flux and apply the flux to the entire joint area with the rod. It is way different than soldering copper or anything else. Product: ALUMIWELD is a welding rod that is able to repair any aluminum metal by using a PROPANE TORCH ! Super Alloy 1 contains cadmium.

Here are some of my practice samples going from 12 gauge aluminum to 14 gauge copper: Before soldering I wrapped the connection with AWG 40 copper wire to hold it together during soldering and to add strength. Soldering Aluminum Cans. Contrary to most claims that aluminum cans cannot be soldered or welded, in fact it can be done. With low heat torches, strong and sturdy welded joints can be created with no flux required. This process is even non-toxic and safe to human and the environment. Read more. I can also drill, but I want to avoid welding. Just make sure to seal the junctions, or you'll have oil dripping out of the seams. You will not find this in your local hardware store. 4.6 out of 5 stars 49. Braze the Aluminum. As the HVAC industry uses more aluminum components, manufacturers need to join these parts—such as evaporator and condenser coils—to secondary copper lines or assemblies. I never used it on a refrigerant tubing though Brazing Aluminum A/C Lines with Weld Strength. Directly make contact to the joints where the metal and the aluminum tubing meets and let stand for few seconds. When creating the hole, take into consideration the size of the hollow aluminum tube. Made with lead and silver, this solder ribbon has greater tensile strength and density than other indium-based solders, giving it a stronger hold. The heat of the metal will … solder: Tinning paste: Contains lead-free solder wire in powder form to clean and pre-tin the pipe surface, which allows solder to easily draw into the joint. As otherwise hinted here, clean the pipe with a brush or better yet a 800 grit wet paper. Likewise, can you solder aluminum AC lines? If instead you want to solder your wire to steel, aluminum, nickle, etc., that’s much harder. Helpful. The torch I'm using has a broad flame so it's probably not as efficient in heating the specific area for welding. Remove the tip and put the end of the solder wire to the heated joint until a slope if formed upon melting. We used a propane torch on the aluminum tubing–at half the melting point of the parent metal. One no-flux old-skool approach is to solder under oil: cooking oil is OK.. In brazing or soldering, joint design and brazing/soldering consumables become key elements for joint integrity.

Much like the solder, the flux should be specialized for aluminum or for the combination of metals you plan to join. Solder – Lining or wiring made of a low-melting point alloy, typically lead or tin or a combination of the two. Solder is a filler metal that goes into the joint between two pieces of pipe. Put the aluminum tubing against the metal to be soldered. To join aluminium and copper using brazing technology and standard NOCOLOK ® Flux, flame brazing would be applicable (as well as using a low-melting flux with a low-melting filler metal). The metal on either side of the joint isn’t melted like in welding, but the solder is. Here I show how to repair a rubbed and leaking air conditioner line which has got a pinhole in it. Brazing Steel Rings with Silver Solder. You will not find this in your local hardware store. You can use a propane torch to braze most metals you want to join. Apply the flame to the joint until it's hot enough to melt the rod. Although these aluminum parts are of differing thicknesses, Super Alloy 5 bonds the metals quickly and easily. SOLDERING Because most aluminum soldering fluxes are corrosive, repair soldering of aluminum refrigeration coils should be done without the use of a flux. Apply the filler metal by running a brazing rod along the crack or the joint. Generally, if you can solder the aluminum, the copper / steel is not a problem. While soldering is generally easy, it becomes more difficult when working with certain materials. Braze Aluminum A/C Lines with Weld Strength. This simply means that prior to welding the steel and aluminum together, the steel is first coated in aluminum. Attach the project to a vice if you have one, otherwise hold it up with the pliers. (I also wanted to solder aluminum to aluminum) I’ve soldered silver to mild steel with the tin solder and if the silver got too hot, the solder would eat right through it. These fluxes are all but impossible to remove when the component being repaired is in place and are difficult to remove even when the part is … I've tried a dozen glues. Question, can you solder copper tubing to Aluminum. 2. Any time metal is being fused together it's always best that you clean it off. Long story short, clean metal sticks to clean metal. I'm using a... Scott. VS. just "heating for a minute" heat the pipe just until you see the flux steam/bubble then introduce the solder to the point of pipe and iron with it applied to the pipe.
