If the flux turns black, your solder won’t flow. On the other hand, liquid propane lessens the risk of burning as the heat is less intense, but still just as effective. The kind of flame used is another reason why problems are encountered when soldering copper pipe. A conical flame can focus too much heat in once place, leading to unwanted ...
Answer (1 of 8): Pipe Soldering 101: The solder will “stick” to (wet) the pipe when the pipe is clean and hot enough to melt the solder. The copper joint areas must be bright clean on both inside and outside mating surfaces. Use emery cloth, or better yet ScotchBrite type of non steel abrasive....
Nov 29, 2020 In other words, keep the solder away from direct exposure to the flame. When the pipe is hot enough to melt the solder remove the flame and continue applying droplets of solder into the joint. Add more heat only if the solder stops flowing before it has wicked all the way around the joint. The truth is I've never used MAPP.
Copper Pipe: If you’re making a repair, you’ll need a short stretch of copper pipe. Otherwise, you’re working on existing copper pipes that need a fitting soldered on. Solder: Also called soldering wire , this is what melts and flows into the joint between two pieces of copper pipe.
Oct 18, 2006 There are only five reasons solder will not flow. This just the first video lesson found on my CD "Understanding Soldering" which contains about an hour of 3...
Mar 14, 2013 The old copper pipe seems thicker and darker than the new, and wont solder for anything. The new pipe and connectors melt the solder and flux, coating the entire joint in seconds. The old pipe will not cover "tin" or solder. No matter how long I heat it with the butane torch, the solder melts but will not stay on the pipe.
Dec 24, 2020 Having proper fittings is important for the solder to flow. If there is nowhere for the solder to go, it will stay on the iron tip. Solder is made for filling holes and not bridging gaps between pieces of metal. Only in specific art forms, like stained glass window making, will the solder be the connecting agent and not the filler.
Answer (1 of 3): There at least two reasons solder won’t melt on a copper pipe. Copper is an excellent conductor of heat. What ever you are using to heat the pipe is not supplying heat. As fast as you heat the pipe the copper will conduct the heat away. If the pipe is a large diameter you can’t ...
Jul 23, 2021 3. APPLYING TOO MUCH FLUX . It can be tempting to use a large glob of flux while soldering. However, we recommend evenly applying a thin layer of this product with an acid brush to copper pipe and the inside of a fitting – any excess flux should be removed prior to connecting them.. Applying too much flux will not only result in uselessly wasted product, but could also cause severe
Why does my solder not stick to copper pipe? Keep pipes dry when soldering Don’t try to solder pipes with water in them. Most of the heat from the torch goes into turning the water to steam, so the copper won’t get hot enough to melt the solder. Stop the trickle of water with a pipe plug.
Jun 13, 2016 Keep going until the seam in the joint looks “full” all the way around but don’t overfill. A handy rule-of-thumb we heard somewhere says to match the length of solder you use on a sweated joint to the diameter of the pipe – a half-inch of solder to do a
Apr 23, 2019 The metal allows the solder to flow, not the flame. Make sure your metal reaches the soldering temperature because that's what counts. You can heat the solder with the direct flame, leave the metal cool, and watch the solder ball up. Without the metal reaching the flow temperature, that ball of solder will just sit there and look pretty.
Brush an ample layer of soldering paste (called flux) around each shiny pipe end, as well as the inside of the coupling. Slip the coupling onto the end of one pipe, and push the other pipe end into the remaining end of the coupling -- position the pipes/coupling in a vertical position in a vise, if practicing installing a vertical copper joint.

Apr 08, 2009 Wipe the joints with a wet rag after soldering to remove the excess flux. Remaining flux will continue to etch (eat) the copper pipe. Deburring/reaming of the cut edges of the pipe is also very important. The sharp edge will create turbulence in the water, causing friction and pipe wear.
Prepping the pipe not only makes the pipe easier to solder but also helps the pipes hold together better by itself. To do this you must know that there are two different parts if a pipe. There is a fitting, and then there are the pipes themselves. The connectors are the larger bit of piping that the pipe fits into.
Mar 27, 2010 I suck at sweating copper pipe. Crafter_Man March 27, 2010, 3:40pm #1. Am running hot cold copper water pipe for a wet bar in the basement. I’ve tried. I really have. I’m using a wire brush, flux, applying the flame to the fitting (not the pipe), etc. and my joints *still *look like crap. Many times the joint won’t take solder, and I ...
The type of solder is important for it to work properly on brass. Yet, it is a common mistake to attempt to use lead solder and not have it work properly. Cut only as much solder as you will need for the joint. You don’t want too much solder. If you are soldering pipes, excess solder could fill up inside the pipe. This could reduce water flow.
How to solder copper pipe and tubing like the pros. Tips, tricks, and techniques on getting a leak free professional solder joint. A complete guide on how to...
A pencil torch coupled with igniters is a good pick for copper pipes of½-inch, or even 3/4-inch. When operating the torch, make sure that you are not soldering at very high temperatures as that may lead to a severed flux and, subsequently, a damaged copper pipe. Plus, if not handled with care, chances of you causing a fire are high.
Dec 20, 2005 Apply flux to copper pipe and the interior of fittings with a small brush. Soldering is the process of joining two copper or brass surfaces with metal. This is accomplished at less than approximately 750 degrees F. When the joint cools, it will be as strong as the copper materials it
The copper must be bright and shiny. Old pipes oxidize on the surface and turn dark- they won’t take solder even with flux. Also be careful heating the pipe too long with a torch. It will change the pipe and soften the copper. Read the full answer. Don’t try to solder pipes with water in them. . Soldering a joint in pipes that contain ...

Re: Old copper pipe does not take solder. Author: sum (FL) yeah no moisture, I suctioned the water out of the pipes to at least 12" or so below. Applied solder to the horizontal end of the elbow, it siphoned in the solder nicely. Applied it to the vertical end of the same fitting, the solder melts and drop down.
Apr 25, 2016 I am attempting to connect two pieces of copper, vertical. Using maps, lead free solder, and flux. Cannot get the solder to stick. Each time I put the flame on, solder melts and runs down the side of the pipe. It does not wick into the opening at all. I also can't seem to get the solder to melt without the maps flame.

Oct 25, 2008 Heat the middle of the fitting as, solder flows to the heat. Keep the flame applied until the flame turns green on the opposite side. Apply solder, and it "sucks" right in. If it's 1/2" pipe apply 1/2" of solder. If it's 1" pipe I usually apply 1" solder. After doing all the steps above like I usually do, the solder in this case melted and flow ...

Make sure the surfaces to be soldered are clean. Turn on the soldering iron and set temperature above the melting point of your solder. 600°- 650°F (316°- 343°C) is a good place to start for lead-based solder and 650°- 700°F (343°- 371°C) for lead-free solder.
All the soldering with the copper pipes has been going ok. But theres one pipe that seems to be giving us a problem. How do you solder the copper pipe with water in it. We have tried sucking the water out with a straw..but that didnt seem to work. It will not solder with even the slightest amount of water. Hope you can help, thanks Edited 1 times.
Simply stick this triangular blunt edged blade into the pipe, and forcefully rotate the pipe and the tool to smooth out the turned-in bur of copper that resulted from the cutting process. This reduces the chance of turbulence and noise developing within the pipe as water is flowing through it
Aug 01, 2005 First, both fitting and pipe end must be cleaned properly. Further, when soldering large copper tubing (2-1/2" and above), both the inside of the fitting and the pipe end needs to be tinned with solder prior to be final assembly. Then the tinned parts are fluxed, put together, then heated with more solder

The solder is not wicking entirely around the joint. The copper is hot enough to melt the solder, but the solder tends to stay at the edge of the fitting - almost like my flux is wax - not flux. With uneven solder flow, it would seam I don't have enough heat. The heat has been sufficient to liquify the solder at the other end of the fitting.

Jul 07, 2010 Soldering the Copper Pipe. When you are ready to begin soldering the pipe, get the blow torch as hot as possible before you apply it to the pipe. The best way to proceed with the solder is to heat up the pipe as quickly as possible. Ensure that the pipe heats the fitting up uniformly, using the blue part of the flame.
The melting point of copper (Cu) alloy UNS C12200 is 1,981°F/1082°C. As such, the filler metals for soldering and brazing copper and copper alloy tube and fittings must have melting temperatures below this temperature. "The basic difference between soldering and brazing is the temperature necessary to melt the filler metal.
Solder has a very low melting point (compared to other metals/alloys). Even a weak 40W iron should melt it almost instantly. If it's not melting the solder, then the iron is not hot enough or even working. The thicker solder requires more heat to melt. Click to see full answer.
Dec 24, 2019 You can’t solder a copper pipe that has water in it. The steam and water don’t allow the pipe to get hot enough to melt the solder. ... You can actually have water flowing out of a pipe at ...
The solder will immediately melt and be drawn into the joint. You do not want to over-do it, because doing so can create a large deposit of solder within the pipe, clogging it or reducing the water flow, or creating turbulence/noise issues within the pipe.
Apr 24, 2018 Touch the solder to the OPPOSITE side of the pipe to see if it will flow. When it does flow, pull away the torch and touch the solder quickly to most of the joint. When it is the right temperature, it will draw the solder all the way into the joint, all around the joint. ... If you would like to stick with copper pipe but not solder you now ...
May 06, 2020 either solder should work although for the cost of copper every time I get ready to do joints a roll of solder and fresh flux is a small investment I have also had problems with 3/4 inch pipe and getting it hot enough with a standard torch , I have a torch that hooks to a LP cylinder and really puts out the heat if you don't get color change in ...
