What kind of welding shall i use to weld copper pipe to aluminum pipe?
use duck tape it works on everything : D i have to agree, adhere it if you can, otherwise use a VERY low heat propane torch. Acetylene burns WAY too hot, and you won't get a good arc going over 2 types of metal. Also, I don't know if you can find a compatible filler rod though. If you do get the metals to stick together, becareful, if wont be very strong. Good luck The proper way to join aluminium pipe to copper is to use a threaded adaptor on the aluminium and add a copper adaptor . you then solder the copper.

The answer is yes. You must first make sure of the following:. There is no gas left in the system(probably not since most likely you are fixing a leak). That if for example you are welding a line by the evaporator the valves at the condenser have the manifold gauges connected and open to atmospher…e. This way the pressure created by the heat will exhaust out the manifold gauges. If not done so the pressure will back up and out of the hole that you are trying to fix and will not allow the weld to cool and seal.. Clean the area to be welded thouroughly. Use silver rod to weld AC pipes and not soldering wire. The weld will be much stronger and last longer ( Full Answer )
Answer . the only way you can weld aluminum is with AC current and high freak setting on the welder , if your welder does not have theses setting then it will not weld aluminum.. Good answer! AC is a must! The only other way is if you have an oxy/ace setup (very low psi) or alot of mapp gas, but… you have to spread a flux paste on the material (looks like drywall mud) EXTREMELY MESSY!

Answer . Pros - quicker (typically 50 to 70% compared to welded pipe), no naked flames, no hot work permits, easily modifiable/extendable, each joint is a union, flexible joints can be used for pipe thermal expansion, curved pipe runs, vibration attenuation, piping in seismic zones.
Answer . DOWN AND DIRTY: For an end or corner joint, cut each intercepting piece at a 45. For T joints, cut the top of the post with two opposing 22.5s to give you a full 45 and cut your top rail with a corresponding 45 to the longitudinal centerline. Peen pieces into place if necessary. Saddle… markers are available at most oilfield supply or welding supply stores. They are available for all common pipe sizes... Simply clamp it on the pipe and mark your cut. No peening necessary.

because the pipes don't rust as easy, and silver and gold are too expensive. That is another persons answer. Here are the main 3 reasons plumbers use copper pipes. Copper pipes are relatively non-toxic-unlike lead. Copper pipes do not suffer corrosion-as iron does. Copper pipes are relatively soft a…nd easy to work with-unlike both iron and lead. However more and more homes are now using the plastic pipe such as Pvc and Cpvc which seems to serve the same purpose and are also safe, although both can be used, you still need to find out what code calls for in your city or town an abide by it.

No. Double Submerged Arc Welded is DSAW; LSAW stands for Longitudinal Submerged Arc Welded. As an aside, HSAW stands for Helically Submerged Arc Welded.. All of these refer to various types of pipe manufacturing processes.
It is malleable and relatively inert. Iron rusts and is very hard. Gold and silver are too expensive.
The pipe must be fixed (not rolled) in the horizontal position. With the pipe horizontal, the weld is vertical. The pipe being fixed requires the welder to weld flat (top), vertical (sides), and overhead (bottom).. The pipe must be fixed (not rolled) in the horizontal position.

tig or mig depending on the wall thickness Copper to copper is either soft soldered, or silver soldered Silver solder is a bad term as "solder" normally means lead content according to the AWS
I have not welded P22, but from what I read it is a low allow stainless that tends to get brittle. The welding techniques specified include a pre and post heat treat and on thicker materials a buffer layer of 316L with the final joint of 309 not sure what p22 pipe is but if it is carbon you should u…se a 308L filler with 100% argon purge 308L is a filler for fusing carbon steel and non carbon stainless. If it were 316 stainless you would want to use a 319 filler P22 is a steel alloy containing 2 1/4% chromium. It is weldable with most carbon steel alloy fillers such as E-70s2, ER-7018, etc. However, to weld it to a low grade stainless steel alloy such as 304, you would need to use a bi-metal welding alloy such as E-309, or ER-309. The above answer is incorrect regarding 308L being a filler for carbon steel to stainless steel. It is in fact 309 which is used for dissimilar metal welding when one component is stainless steel. I have also had good success welding two dissimilar metals together using inconel alloy welding electrodes such as INCO-182. ( Full Answer )
Because it lasts and is very versatile and can be used for a variety of plumbing applications with amazing results
The answer is entirely dependent on the material/s you are welding. Consult ASME for your specific application.
By turn a cable a number of turns around the pipe. A DC current flowing through the coil will generate an electrical magnet to oppose the residual magnet in the pipe. if not work, may be you need to increase the number of turns or to reverse the DC current flow.
Firstly you have to take out the width of the groove, for finding the width of the groove you have to apply tan formula, then after finding it you have to calculate area of the v-groove with respect to formula of area of triangle i.e.1/2 x b x h x l. then you have to find the volume of the electro…de which are you going to use i.e pie/4 x d square x l . after finding this you have to divide area of triangle to volume of cylinder, whatever you get is the consumption of electrode in that much of thickness, and you will get the no.of electrodes which are to be used in that much of thickness, if any query or suggestions please give suggestions on my mail i.d is firstname.lastname@example.org 96241 80135 ( Full Answer )
Seamless (SMLS) pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. Seamless pipe withstands pressure better than other types, and is often more easily available than welded pipe. Welded pipe is formed by rolling plate and welding the seam. The weld flash can… be removed from the outside or inside surfaces using a scarfing blade. The weld zone can also be heat treated to make the seam less visible. ( Full Answer )
Because it doesn't rust, it doesn't break down, and it doesn't cause any impurities in the water. - More specifically, copper oxidizes into a stable compound, keeping it from corroding through. It also is naturally anti-bacterial. The most important reason,though, is that copper is easy to wo…rk and shape with hand tools, a necessity to fit pipe into places inside houses and buildings. Copper can be brazed into joints with hand equipment, and cut with a small tool, rather than a large pair of iron shears. ( Full Answer )
Copper is used for wiring because it is a good electrical conductor and it is easily drawn into wires.. Copper is used in plumbing because it is easily shaped to form pipes. The fact that it is a good conductor also permits the piping to be used for electrical grounding in some cases.
Copper is used as it is a very unreactive metal and it does not oxidise easily. it will not rust and is in more advanced terms non ferrous. It is also preferred by plumbers as it is easy to manufacture and shape as it is a soft metal
Because of following reasons . Copper is economical. . Copper is lightweight . Copper is formable . Copper is easy to join . Copper is safe . Copper is dependable . Copper is long-lasting . Copper is 100% recyclable
The only methods for demagnetization that I have seen work include heat treatment and magnetic induction. Heat treatment can be performed with electric resistance coils or an oxy-fuel torch, heating the pipe to a dull cherry red and holding it at that temperature for several minutes, then allowing t…o cool to ambient over a long period of time. The other method is usually effective and much simpler and does not affect the metallurgical integrity of the pipe as heat input can. This method includes taking the positive welding lead and coiling it around the pipe near the joint to be welded. Several coils should be made tight to the pipe and each other, then induce current through the lead by welding for a few minutes on a piece of scrap or something just to allow current flow through the coiled welding cable. You are essentially turning the pipe into a big electromagnet by doing this. If it doesn't work the first time, try reversing the direction that the lead is coiled around the pipe and induce currrent flow again. More often than not, this will demagnetize the pipe enough so that the weld can be made. (Uncoil the leads from around the pipe before making the pipe weld) ( Full Answer )
Furnace butt welded pipe refers to the manner in which a pipe is tobe welded. The skelp itself is heated to a specific temperature ina furnace. You would then weld the longitudinal seam forge. This isa method that works on fence posts or pipes required for lowpressure services.
Fusion welding is just any welding process which inhibites the phase trasition from solid to liquid and then back to solid state, while electric resistance welding is based on purely ohmic heating of the different parts, this heat will create fusion of the metal. So; Electric resistance welding can …be said to be a type of fusion welding, but not the other way around. ( Full Answer )
Double submerged arc welded pipes has two types, one is spiral welded pipes, and the other is longitudinal welded pipes which are different from EFW pipes.
No. It is only efficient up to 500degrees Fahrenheit and most of the exhaust system will normally get hotter than that. You need proprietary exhaust repair material or a professional weld.
A welded pipe has a visible seam. -That's a little clue about why they call the other kind 'seamless' .
I would use a wire feed MIG, or a oxy-fuel torch. If arc welding, use a low power. It's really easy to burn through exhaust pipes and mufflers.
E7018---- I'm adding this to the answer. Never having welded rail I have seen a video of one process. It is called Thermite Welding. A mold or dam is built around the joint where rail ends meet. A mixture of Aluminum Oxide and iron powder is poured into the mold and ignited. The mixture burns at a v…ery high temperature melting the iron powder and the ends of the rails. After cooling the slag is hammered off and the extra weld metal is ground to the shape of the rail. Google Thermite welding. A video is available. ( Full Answer )
Gi weld not recommended . Because of gi coationg will be spoiled out . Puncture will be occur on the pipe weld .
Yes. I've used it on aluminum as a permanent repair. I'd recommend prepping the surface thoroughly.
Very likely to leak, zinc in the GI pipe will be contaiminating the weld and thus you cannot get a good weld.
Yes, and No, Nitrogen can be used to purge gas lines prior to welding, but the correct answer depends on several things, mainly, your welding application. A significant amount of resistance welding applications use N2 as a suitable environment for welding. Other applications use N2 as a purge gas, a…nd then purge the N2 with the process gas. That said, if you were going to be using a different inert gas (Argon, Helium, Xenon, etc.) to provide the actual the actual shield for the weld, then you would still need to displace (purge) the N2 from the lines. The last statement leads to the question of; if you are going to have to purge the lines anyway, why do it twice? The answer to this question is pretty basic. Nitrogen is cheap. If you had to purge a lot of lines, or a large volume of space, you would rather use N2 to drive out the Oxygen and lower the dew point (moisture). Using one of the other welding gases would cost about ten times as much to perform the operation. ( Full Answer )
I am assuming you are concerned about the fumes produced #1 or maybe whether the galvanized coating should be removed prior to welding #2. #1 Galvanizing is usually a hot dipped process that contains zinc. Zinc can make you extremely ill and possibly kill you. Low doses give you zinc chills. Sympton…s feel like malaria. You can tell when you are being exposed to too much as it begins to smell sweet. Weld with plenty of ventilation. Upwind of air movement is best. #2 Zinc burns fiercely and vaporizes well below the temperature of the arc. It mixes with the weld creating a poor weld. Grinding off the zinc prior to welding greatly reduces this effect. Painting with a zinc coating while the pipe is still hot is recommended. ( Full Answer )
I am sorry, but can you PLEASE rephrase your question? Can WHAT be used for copper pipe? When? How? Why?
It greatly depends on material cost and the labour cost. In middleeast region, it is around USD 10 / Inch dia for CS welding
Metal expands as it is heated and contracts as it cools. Keeping the heat input even, completely around the pipe, will help. If possible reheating the weld area after the weld is complete can help to "stress relieve" the joint. Using a weld "fixture" to prevent bending is another possibility.
No, it won't stick to most PVC. Oatey's Transition Cement and most epoxies will work IF the PVC is dry.
Wet underwater welding is possible but not easy to get a good quality weld. Hyperbaric welding underwater is performed in "dry" conditions underwater in a hyperbaric habitat. Usually the pipe needs to be pulled to surface, by either diver-assisted or diverless means. All of this is routine work in o…ffshore engineering and construction, and is usually very expensive because of the specialist vessels and personnel required. ( Full Answer )
There is no answer. There are to many factors to generate an accurate response. When estimating, your best bet is to refer to similar jobs that your company and employees have completed. Those production rates will be the most accurate. When quantifying weld per inch Dia. Given varying degrees of en…vironmental restrictions, wall thickness, procedure, pipe type and size, the hang over that your crew has from the night before and the rest of the equation it is difficult to determine what production rates will be. My recommendation is to use previous proven production rates and work on improving the management coordination, material and equipment supply and communication to the crew. if focus is given in these areas a substantial increase in previously realized production rates will be seen.

It's due to a combination of factors. Copper is a very good conductor of heat, which is pretty much the most important need for heating/cooling systems. And it is widely available, in multiple sizes, and can be worked with conventional tools including soldering torches and so forth. It has more than… adequate strength. And does not corrode like iron pipe. Is resistant to breakage during cold weather. And, historically copper (one of the metals known for centuries by man) has been very low in cost. Oh, and it can be joined to other metals, like aluminum and steel in several ways, helping to decrease the manufacturing cost of these systems. ( Full Answer )
welded pipe is a pipe made joining using weld metal to make it a pipe..and a seamless is made like moulding
Grind the surface of GI pipe lightly to remove the skin which is about 0.1 to 0.2 mm, than weld the MS pipe as per the wall thickness and use accordingly the welding rod at the required gauge / Dia of the welding rod. this works fine.
If you're talking about water service to a home, copper used to be used from the late 70's through the early 90's. With the advent of plastic piping, the cost for installing this type of piping is dramatically reduced. Also, many soils throughout the country have a high metal content which creates e…lectrolysis with the copper pipe causing premature failure of that pipe. Plastic pies don't have to worry about that. So, its mostly a money issue. ( Full Answer )
There are size on size weldolets. The hold on the run pipe will necessarily be undersize (either hot tap or torch ) because it's not possible to cut the same size hole in the run without damaging the base material.
It is usually done by a form of hot air welding. You would have to find out more from the supplier or manufacturer of the particular pipe in question.
Yes. Argon gas welding is often used for killed steel welding to inhibit the oxidation of the steel.
Welding should only be done between similar metals. Installing welded flanges to connect two dissimilar metals would be the preferred method of connection.
It is the only type of weld you can make to seal this type of joint. There are flange ends that can be welded onto pipe with a butt weld, but sockets and slip-ons must be fillet welded.
The best sealers for copper pipe are a combination of plumbers tape and plumbers epoxy. The tape is used to temporarily seal any holes while the epoxy dries.
A GI pipe is welded to a GI pipe by using solder and flux. The pipe is heated up, flux applied, and then solder allowed to flow into the joints to create a secure bond.
You can solder copper very effectively. However, there are so many better ways now, i virtually never solder. In this case I generally cut out the bad piece of copper and fit PEX between two Sharkbites or compression couplings. Many of the buildings I work in are built of very dry old wood so solder…ing is not ideal. ( Full Answer )
