Funny how you never see anyone TIG welding with coat hangers. "author": { Moreover, you have to know the strength of the propane torch and whether the torch is able to perform brazing and soldering or not. Moreover, the parts of the brazing operation should also not lose energy. Both steel and aluminum can be welded with either process, but fusion welding is trickier. Never had one fail. A propane torch can reach up to double the temperature of aluminum metals. A propane torch simply cannot produce sufficient heat to perform fusion welding successfully. The ads you are seeing are for those magic rods for welding aluminum with a propane torch. Make sure to fill up the gap between the two metal pieces to provide a strong and long-lasting connection. Steel filler is used without a flux; actually the neutral torch flame is the flux. > It's more closely related to brazing, but it's not brazing because there's no brass involved. But, you must have precise welding skills to weld thin-walled tubes with this type of torch. Avoid moving the flame too slowly as this will overheat the metal. Hooking up a muffler without welding is possible if you know the correct method. Friends got a hold of some thick steel cable and I am talking over an inch thick with the wires an eighth of an inch thick. These metals need different temperatures to be brazed. I haven't bought rod in a long time as I have plenty, it was once a preferred method of welding thinner metals before mig welders became affordable. I think those magic aluminum welding rods melt at around 730F, so I guess their process is technically soldering rather than brazing. Back in the 70's we used coat hangers in the Army to weld exhaust pipe. Dont forget to keep the flame next to the welding area to minimize affecting the other untreated spots. If the surface is not clean, the solder will lose its strength and fall apart. But you must prepare the surface and use a proper type of propane torch. A good drill will cut either of the 2. The final part follows a straight line toward the welding seam and keeps the torch moving. The coper-brass collord rods are for brazing, not welding. Can You Weld Stainless Steel with a Blowtorch? Google gas welding rod for info on many types. However, it takes around 20-30 minutes to complete a welding session for a muffler. A welding torch is a mechanical device that melts pieces of metal. If your propane torch keeps switching itself off, the vent holes could be filled and starving the flame of oxygen to mix with the propane. It welded good anyways. For doing this, you have to choose an environment where energy loss is limited. ESP Malfunction On Ford (Here Is How To Fix). Regardless of which metal fabrication type you choose, here are a few tips that can help you end up with a better weld: Welding with a blow can be a good entry into the world of welding since the materials are easily accessible, and the process isnt as complicated as a technique like TIG welding. Brazing rods are typically flux-coated, although you can buy the flux separately. I do not know how many types are available, but I do know and have used rods for steel, brass rods for brazing, and rods for welding cast iron. Position the metal as desired. Cutting. The main application for MAPP gas in blowtorch welding is in underwater welding, where it acts as a safer alternative to acetylene (which reacts explosively when exposed to high-pressure environments). It is easier to achieve a weld with a propane torch than a butane one, but propane is only suitable for brazing particular metals such as silver solder and to braze brass. Although propane flames may reach temperatures twice as hot as the melting point of aluminum, aluminum properties make it highly conductive and radiant in relation to heat. If you want to weld light material, say 10 gauge or less, you can do fusion welding with most oxyacetylene torches. You have to keep in mind that 90% of a blowtorchs heat is dissipated through contact with the air, which makes it one of the least efficient welding methods without a shield. Can You Run an Attic Fan with the AC On? Move the welding torch in short runs so that you can ensure youre getting the result you want without having to adjust the fuel-oxygen mixture. one is a machinery repair shop and sells both new and ysed horse drawn machinery, other is his cousin and is a horse machinery jocky and runs a construction crew so he gets to a lot of places, that is how he found that heavy cable. For what little I weld with gas I just grab a coat hanger! Richard in NW SC Coat hangers are cheap and readily available also. I've been welding a long time. Propane torches are categorized as air-fuel torches because they use a mixture of propane gas and oxygen. Be sure to remove any flammable objects or liquids like gasoline or cleaning agents from the workspace area to prevent accidental combustion. It takes about 850*F to melt brazing rod. This step is the main step of soldering. Generally, you will need a high-temperature torch to raise the temperature high enough to braze the copper pipe. So, you will need a high temperature. Both pipes should be on the ideal spot relaxedly. It stands on the tail in the back and on two feet in the front. Welding metals and joining them is his hobby and he has also got a vocational training on welding. Here aresome toolsthat I use daily and hope youll also find helpful.

Yes, the right sort of propane torch will get enough hot to braze. Brazing is a process; it doesn't require brass or bronze as a filler. You can O/A or tig weld with a coat hanger as filler. You can also use a propane torch to braze brass. However, in most cases, propane torch can solder well. Hence, its better to observe it from time to time. Generally, the brazing process joins two metals permanently. Both the gauge guards and the valve guard are made of sheet steel IIRC. They are an inexpensive source of heat and fuel for welding applications in comparison to TIG or MIG set-ups, They are a clean-burning source of energy, They are recyclable and environmentally friendly. Gold melts at above 1,974 (1,064), and it seems logical that butane, reaching 1,430 C (2,610 F) would be ample heat to melt gold. Allow the weld to set and harden overnight. Here, we will walk you through the perfect way to weld a muffler using a torch. Because brazing copper pipe requires more heat and high temperature than other metals. Copyright 2022 OneHappyLemon | Privacy Policy, Curtain Rod Distance from Window (Complete Guide), Garage Drywall Thickness (Complete Guide). I think they use a regular brazing rod for that.

Its blue color gives you an indication that the temperature has already reached in perfect level for welding the muffler. Once properly cured, you can test the joint by keeping a load under it. For heavier stuff, brazing is easier because it doesn't require so much heat. There are affiliate links, so if you do decide to use any of them, Ill earn a small commission. } If needed, use clamps to secure the pieces in position. You can make it higher or lower by opening or closing the oxygen valve of the tank. For what little I weld with gas I just grab a coat hanger! Welding is an age-long mechanical practice for joining different metals. Proper welding filler rods are made from certified, traceable steel containing alloying elements, anti-oxidizers, and a known carbon content. You can use TiG rods from the welding shop. Nothing special about the rods. copper coated. Either 1/8 or 1/16 dia. You can either use a propane torch for providing the heat. Its one of the first procedures that was taught in welding school. Generally, we braze and solder materials for different purposes. If the muffler is too old, extra time may be required to create a stronger bond between the two metal pieces. Yes, you can weld aluminum with a propane torch and aluminum brazing rods as long as it is for non-structural metals that are not weighted or stressed or critical parts. Even ordinary household propane will work well to solder silver. But this would require continuous flame proximity over some time. No, butane torches do not reach a high enough level of heat and energy to be able to braze or weld metals efficiently. Most aluminum alloys are capable of being brazed, though propane blowtorches are not capable of reaching the temperatures capable of performing aluminum welds. 31, Eye and Face Protection for Welding and Cutting Operations, available from American When I first went to welding school that was the first thing they taught. Friends got a hold of some thick steel cable and I am talking over an inch thick with the wires an eighth of an inch thick. It's kind of a lost art. Tried the coat hanger trick. However, the plant that manufactured MAPP gas discontinued its use after it was discovered that the high levels of hydrogen present in the gas mixture rendered steel welding applications brittle in comparison to other welding gas mixtures. Make sure that youre already wearing your face shield, thick gloves, and safety goggles first before you even start with anything. Move the tank's fuel knob, usually located near the collar of the torch attachment, to the "Open" or "On" position. When I first went to welding school that was the first thing they taught. But you can braze with a propane torch with a limited heat loss. Ended up with a big puddle of plastic. These methods use high temperatures to melt the joining metals. What kind of torch? I think those magic aluminum welding rods melt at around 730F, so I guess their process is technically soldering rather than brazing. Once youre done lighting the torch, you can now get the materials or metals you will weld.

However, you may use a butane torch for brazing and soldering standard copper pipes and tubes found in most households plumbing. While a blowtorch isnt the appropriate tool for all welding jobs, those welders who are used to higher-powered welding tools such as TIG units might be surprised at the kind of metal fabrication projects that can be accomplished with a simple propane blowtorch. But the best option depends on the condition of your muffler. Braze welding is a type of welding where, instead of the two pieces of metal being fused at the site of the weld, a filler metal alloy is used to patch the two metals together like a sort of glue. Keep reading to learn more about braze welding. Here are some of my favorite tools & equipments. Lets see how you can do it. Welding a muffler with a torch is possible if you follow the right approach. You can cool the sample at room temperature. It needs to provide a considerable amount of heat and thermal energy to weld the metal of mufflers. Adding a good quality chemical flux can help you reduce the probability of unwanted fault in the welding joint. This produces a small amount of fuel in the torch's spark cup. So, you can solder with a propane torch by yourself. It's an old welding process predating the electric arc welder. Its also important that the weld bead you lay down is long and wide enough to cover the crater created by the weld pool sufficiently. Even a propane torch can work better than other torches. Braze welding is considered a variant to MIG/MAG welding and is performed by melting a filler metal and then flowing it into the joint of the metal assembly. Most likely the advertised rods are actually brazing rods. Ellis, Sometimes I read something here that leads me to google search for more info on the subject. Keep in mind that you should never use a butane lighter when lighting a propane torch because it is extremely combustible and is not suitable to be placed near a propane gas. Preheat the welding area in alloys and higher carbon metals to prevent post-weld cracking. 1. You may need an adapter to take the correct measurement of the muffler. Sometimes coat hangers are all you have. Default; Price from Low to High . But make sure that you use proper flux material before soldering with a propane torch. Take your pick.
