And it also is forced into the fitting. Creating a watertight seal.
What is soldering copper?
The process of joining copper pipe and fitting is called soldering (or sweating), which is a critical step in the copper installation process. Solder is a metal or metallic alloy that historically consisted of lead (known as lead-based solder) and tin in various proportions. Today, due to the Safe Water Drinking Act and lead-free restrictions, solders that contain more than 0.2% lead are not permitted for use in potable water systems.
What happens if you don't prep a pipe for soldering?
Otherwise, it is likely that the solder will not completely fill the cup of the fitting, resulting in a weak or leaky joint.
What happens when you heat a copper fitting?
When heating the fitting to sweat the copper pipe, make sure you remove the flame as soon the solder melts. As solder melts, flux will pull the solder into the fitting cup. Too much heat will cause excess solder flow or flux to burn out, which will increase the chance of a leak path.
What is silver bearing solder?
Silver-bearing solder: Contains silver, copper, bismuth and tin. Lead-free and safe for water supply lines. Ideal for low-lead brass applications. Has a wide melting range (420°F to 460°F) that enables more time for soldering joints.
Is solder safe for potable water?
Solders that are safe to use on potable water systems contain a percentage of tin and a combination of other non-toxic metals. The melting point of solder is lower than copper, and when heated, solder melts and fuses the piping together once completely cooled.
Can you use flux while soldering?
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.
Is copper pipe safe to drink?
Copper is the metal of choice for potable water systems for a variety of reasons – the most important being that it is non-toxic and safe for drinking. The naturally occurring metal element is also preferred for various application types due to its high conductivity of electricity and heat, corrosion/fire resistance and durability.
What Solder for Copper Pipe?

Do copper pipes leak water?
Copper pipes are still in the majority of homes today even though new home construction is moving to PEX piping for water delivery. In order to join pipes together it’s necessary to solder the joints together so they don’t leak water. The water pressure inside a typical house should be between 40 psi and 80 psi. If there was a leak you’d have a lot of water exiting and making a large mess.
Do you need solder for sweat pipes?
Are you adding a bathroom in the basement or need to move some water supply lines around? If you do your own plumbing work and sweat pipes, you’ll have your own torch but may need some solder. Many DIY’ers want to learn how to do their own plumbing work and this is a great way to learn. Always maintain respect for the skilled trades but sometimes there are small jobs that you can do yourself. Let the professionals do the medium to large jobs. Ready to see the best solder for sweating those copper pipes? Let’s get right to it!
Do You Need Flux to Solder Copper Pipe?
Flux is not necessary but it’s very difficult without it. Without flux, the copper will oxidize as it heats up and will prevent a good fit as you put the fittings on the pipe. The flux will prevent the oxidation process from starting and allow the pipe to heat up so you can melt the solder when you add it to the pipe.
What is brazing solder?
Brazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a material into the joint, the filler material having a lower melting point than the adjoining metal. The difference between brazing and soldering is the temperature necessary to melt that filler metal.
What is the difference between brazing and soldering?
The difference between brazing and soldering is the temperature necessary to melt that filler metal. That temperature is defined to be 842ºF/450ºC by the American Welding Society (AWS) but is often rounded to 840ºF. If the filler metal melts below 840ºF the process being performed is soldering.
Why do you heat the pipe?
The first part you wanna to heat is the pipe, the reason being is that between the fitting and the pipe is a small gap of air. Seeing air doesn’t transfer heat very well, it has to be heated independently, in the beginning, to make sure it reaches brazing temperatures.
Why is it important to wet a pipe?
This step is very important, as “proper wetting” is somewhat influenced by the pipe and fitting’s cleanliness. Wetting is the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together.
Can filler material fuse?
In other words, your filler material won’t fuse properly if they aren’t perfectly clean. Also, de-burr the inside of the pipe using either a round file or a dedicated pen reamer. Now’s a good time to choose what tip you’ll be using for your application.
Can a propane torch be used for soldering?
And finally, the torch. When soldering, a torch like this is used seeing only one gas is needed. Plus, propane torches don’t give out near as much heat as an oxy/acetylene torch does.
Can you use air acetylene for joint cleaning?
You could use a simple air/acetylene setup like this, but it’s considerably longer and doesn’t give you a clean joint like an oxy/acetylene kit does. However, they are more economical and lighter to carry around in tight spaces, so use what’s best for you.
