Techniques that carry plumbing water pipes in the house is actually a blend of copper pipe that you can solder to tin-free torch. To replace the torch, you can use a single lamp to heat because the welding of a copper pipe does not require complex assembly, such as hot water pipes or gas that require greater strength.
All the copper pipes can easily be made by the process of welding tin and does not require the use of a torch. It is first important to know some basic techniques of welding to achieve a good weld that joins the pipes properly. The welding of copper is a relatively easy to perform and which does not take much time, you can do it yourself and it only takes a few tens of minutes. In addition, it will cost cheaper than calling a professional plumber or tradesman who will do the same work as a whole. There are many sites and videos of yourself on the internet that you can learn first before you jump in the welding of copper. You’ll find them mainly on the forums yourself in the plumbing section.
Preparation of copper tubing before welding
To properly perform a welding torch without copper, you can instead use a simple heat lamp. It is advisable to also use gloves and safety glasses to prevent burns. It is very important to clean first copper pipes with an emery cloth. Make sure that the lower and outer pipes are clean so that the weld is highly successful and leaking. You will need in addition to the heat lamp, have on hand for the solder to the connection between the pipes. It is advisable to put a little solder flux on the pipes to avoid that copper does not oxidize when heated.
Then you can start to cut pieces of pipe needed. You can cut copper pipe with a metal saw or pipe cutter. Can you use a file to remove burrs formed when cutting your pipes. You will also need a steel wool, abrasive paper and a brush to clean metal parts that will be in contact with the solder. It is important to clean these parts so that the pipes are brightest, this will remove the oxidized copper or any contaminates. To avoid unpleasant surprises, first assemble the scattered pieces of pipe to see if the pipe is the right length and for easy assembly.
The welding of copper pipes without torch
Once all the pipes are well prepared and ready, you can start putting a little solder flux on all joints you want to weld. Then put the two pipe surfaces in contact, and make sure that the outside gets the inside properly. Then placing the pipes and make sure that they are well capitalized as your two hands will be occupied after soldering. Using your heat lamp, first warm the gasket on the bulk or the pipe is inserted. Continue this process until the pipe is hot enough to melt the tin can on the joint. It is important that the tin is melted, because this is what will seal the two pipes.
The tin must be melted steadily as a common cold may cause a suction that will suck in the opening between the two pipes. Be sure to add tin continuously during welding, as a slight decrease can cause a channel and possibly a leak. Go around the pipe with the soldering tin wire and check that all joints are filled. When the tin wire on the pipe begins to remain well bonded to the solder, you can stop to add more. Do not worry if there are any burrs during welding, the important thing is that tin is properly inserted in the joints and especially around pipes. After completing the assembly of your new plumbing, it is important to test to see if there are no leaks. Simply introducing a little water in the pipes while remaining near the safety valve in case of emergency. Then you will just open the valve by increasing the pressure gradually and check one by one the welds.
