What'' s up individuals and also welcome back to
another back to basics video clip. If you aren'' t already SUBSCRIBED to the channel
go ahead as well as SUBSCRIBE as well as make use of the bell symbol right next to it to be informed of
upcoming video clips. Today I'' ll be explaining to
you how to appropriately braze a copper joint. There are three simple actions to
getting this accomplished, the very first step is to prepare the joint. Avoiding this step may lead to a poorly brazed joint. Tip two is the actual brazing process which I'' ll reach in just a min, and tip 3 completing off the joint. Alright so allow me start by describing what brazing is, then mentioning the distinctions between brazing and soldering. Brazing is a metal signing up with process in which two or more metal things are collaborated by melting and also streaming a material right into the joint the filler product having a reduced melting factor than the adjoining metal. The difference in between brazing as well as soldering is the temperature necessary to thaw that filler steel, that temperature is defined to be 842 degrees Fahrenheit or 450 degrees Celsius by the American Welding Society, but is commonly rounded to 840 levels Fahrenheit.If the filler steel melts below 140 levels Fahrenheit the procedure being executed is soldering.
Brazed joints are used for refrigeration, high stress airlines and also heating and cooling where maximum joint stamina is a should and also solder joints are used in low stress applications such as drinkable water lines and also some home heating systems. The devices as well as sort of filler
products vary from a solder joint to a. braze joint so allow ' s undergo both of them together.When soldering drinkable water. lines, you ' ll be making use of

this kind of solder which is called 95/5. This kind of. solder can ' t be used when brazing so you ' re gon na be needing a filler. material such as this. There are numerous kinds of filler products on the market. and you ' ll requirement to choose the ideal one relying on the kind of task you ' re. doing. In case of any type of doubts, put on ' t be reluctant to. ask your local pipes supply look for what type of rod you require to utilize for. your application. For this presentation, I ' ll be making use of a stay-silv 15 pole which. consists of 80% copper, 15 %silver as well as
5% phosphorus. You ' ll wish to obtain a. pole that includes phosphorus as
their self fluxing, removing the requirement to use any type of change on the pipeline. Seeing silver solder thaws at a much. greater temperature level, you ' ll be needing even more heat than your typical soldered joint. Brazing smaller sized pipes is feasible with a small gas torch however larger pipelines. such as 1-inch as well as up, need more warm, consequently it ' s advised to use an. oxy-acetylene system with an ideal torch seeing silver solder melts at a much. higher temperature level than regular solder.Oxy-acetylene burns much hotter at 3500. levels Celsius or 6330 degrees Fahrenheit contrasted to propane.
which burns at around 1995 levels Celsius or 3620 levels Fahrenheit,
as well as ultimately the lantern. When soldering, a torch similar to this is made use of. seeing just one kind of gas is needed. Plus, propane lanterns put on ' t hand out near. as much heat as the complying with, the oxy acetylene torch. I ' m utilizing this
oxy. acetylene Port-a-torch set from Harris which is a Lincoln Electric Firm and also.
is excellent for light responsibility brazing tasks such as this one. It can be found in a transportation. tote and also there are 2 containers, one for oxygen and also one for acetylene.There ' s. also 2 regulatory authorities for each gas and also the actual lantern. You ' ll additionally notice the.

torch'tips that feature the set, yet we ' ll discuss these later in the'. video.
You might utilize an easy air acetylene setup similar to this but it ' s. considerably longer and also doesn ' t provide you a clean joint like an oxy-acetylene package. does.
Nonetheless, they are extra affordable and lighter to lug around in limited. areas, so use what ' s best for you. Something else you may wish to. take into consideration is making certain your torch has flashback arrestors on both the oxygen. as well as acetylene side.
Many brand-new torches featured them constructed in.In the past, these. were different and needed to be installed on the pipe itself, so simply make certain. your kit is furnished with them as they '
ll quit a fire from going right into. your container, which you don ' t truly desire
. A few other things I ' ll be stating in'. the video are some cord brushes, an assessment mirror as well as a fire. extinguisher. Alright, so with that out of the method, let ' s start! If your. brazing on a refrigeration or cooling down system with expensive elements, it ' s. highly advised to purge your lines with an inert gas such as ARGON or. NITROGEN. Throughout the brazing procedure, a lot of oxidation will certainly take place inside the. pipe, creating range that might potentially obstruct these pricey parts. and even, invalidate a warranty! In this presentation, I ' ll be missing. this step. So the initial point that requires to
be done is to cleanse our pipe and. fitting. For the pipe, I'either utilize some sandpaper such as this or simply an abrasive. pad. This step is extremely important as appropriate “wetting” is rather affected by. the pipe and suitable ' s cleanliness.WETTING is the capability of a fluid to. keep contact with a strong surface arising from intermolecular.
communications when the'2 are united. Simply put, your filler.
product won ' t fuse correctly if they aren ' t perfectly tidy. Also deburr the. within the pipeline making use of either a round data or a specialized pen reamer such as this. one. Now ' s a great time to pick what tip you ' ll be making use of for your application. Each supplier includes a graph that
specifies what pointer you need for. whatever density of product you ' re dealing with. For this demonstration I ' ll. be making use of a second pointer from Harris. Once both storage tanks have actually been filled up,'provide. them a fast purge to ensure no contaminants are entering into the lantern. assembly.Install both regulators, after that link both of your hose pipes and finally. the torch. Now open both storage tanks and readjust
both regulatory authorities to around 5 psi. Once full stress is gotten to on the oxygen side, you can completely open up the. shutoff. On the acetylene side however, it ' s advised to open up the valve only a. quarter turn after the scale reaches full pressure, this will enable very easy. closure if a crash takes place. Extra pressure than this will cause an.
unpredictable fire so I advise sticking to these numbers. Additionally, making use of the very same.
pressure on both tanks means they ' ll deplete similarly which implies one trip to.
fill up instead of two. Go in advance as well as first open up the acetylene knob regarding midway.
and also light completion of the lantern with a striker similar to this.
You ' ll see a mix of. residue as well as smoke airborne, this is typical, just wait for both of. them to get rid of up as well as gradually open the oxygen'side.
There are three kinds of. fires, one you don ' t desire is a carburizing flame, right here ' s what a. carburizing fire looks like. It ' s conveniently distinguished by its 3 colors and.
lead ' s to extreme carbonization on the pipe which isn ' t essential and could. endanger the joint.Secondly, is an oxidizing fire which you'put on ' t want.
either.
How To Silver Solder (Braze) A Copper Pipe (A/C Line Repair) | GOT2LEARN
This sort of fire, as the name states will oxidize your job item
. which is undesirable. And lastly, a neutral fire. A neutral fire is what you ' re. searching for as it doesn ' t carburized neither oxidize,'it has an ideal mix'of. oxygen and acetylene and also is typically a clear blue shade such as this. Before. brazing make certain your pipelines are well supported and also make certain to have a fire. extinguisher just as a precaution. The first part you wan na warmth is the pipe.
The factor being is that in between the suitable and the pipeline is a small space of. air. Seeing air doesn ' t transfer heat really well, it has to be heated up.
individually in the starting to make certain it gets to brazing temperature levels. As soon as the pipeline has actually been warmed, begin heating up the fitting ' s center, always remaining. in motion.Every occasionally utilize your filler product to check if it ' s warm.
sufficient and as soon as it is you ' ll see it begin to melt.
Now, you'desire to. ensure you don '
t warmth the actual filler product you desire the heat from. the joint to melt it so to make certain
you do it properly, don ' t use any. focused heat on the actual brazing pole itself. You may discover your pipeline. ending up being red-hot however, wear ' t usage a lot more heat than that regarding not overheat it. As I.
mentioned earlier, appropriate wetting is essential when brazing as well as overheating the.
joint will inhibit correct capillary action. Capillary activity is the capacity.
of a fluid to flow in slim areas without the assistance of or perhaps in.
resistance to outside pressures like gravity. An example of capillary.
action is when a paintbrush or paper towel is dipped in a liquid.The fluid.
is taken in without the help of exterior forces. When you feel that that joint is.
completely filled up, apply a little “” filet”” or cap where both the pipeline as well as installation.
meet. An appropriate filet or cap should be scooped much like this. When you'' re. finished brazing slowly close the oxygen knob on the torch.
complied with by the acetylene handle and afterwards close both tank shutoffs to make certain no.
gases are passing through.I constantly like to
remove my hoses prior to stating I ' m. completely done.
With your joint effectively brazed, wait on it to cool down. normally.
Using water to a heated pipeline because of this could cause a crack in.
the joint resulting in a dripping joint. Once the joint is cooled, get your.
wire brush as well as get rid of any scaling that took place on the surface of the pipe.You.
intend to be able to evaluate your work and see to it that there aren'' t any kind of gaps. If.
you'' re in a limited area, a mirror might aid you analyze your joint to see if.
any kind of modifications may be needed. Right here'' s an example of a removed line versus a non.
removed line. As you can see, there suffice contaminants that formed within.
the pipeline the obstruction a metering gadget or whatnot, the distinction is obvious and also.
ought to be taken right into factor to consider when brazing on pricey tools. And.
that'' s exactly how to correctly silver solder or braze a copper joint. If you'' d like to. see a fantastic instance on just how to correctly solder a copper pipe I'' ll placed a link in.
the description box below that links to it in this video.You ' ll learn all the. required steps to correctly solder a copper joined with ease and also with extremely. standard tools.
