What kind of welding shall i use to weld copper pipe to aluminum pipe?

already exists.

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

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.

Can you weld air conditioner pipes where freon flows from?

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 atmosphere. 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

How do you use your portable welder to weld aluminum?

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!

What are the Pros and Cons of using Victaulic pipe fittings versus welded in HVAC applications?

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.

How do you cut pipe ends for welding perpendicular joints?

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.

Why is copper used for heating pipes?

Because it is EASY to use FAST to install gives up heat faster then steel or cast Iron and just about anyone above the age of 4 can solder it and it is light to handle

Type of weld for Lsaw pipes are double submerged arc welding?

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.

Why is copper used for piping?

It is malleable and relatively inert. Iron rusts and is very hard. Gold and silver are too expensive.

In the 5G position for welding pipe the pipe must?

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. With the pipe horizontal, the weld is vertical. The pipe being fixed requires the welder to weld flat (top), vertical (sides), and overhead (bottom).

How do you weld copper pipe to copper pipe - not brazed?

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

What is the welding procedure for welding P22 pipe to 304 stainless pipe?

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 use 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.

Why is copper pipe used for plumbing?

Because it lasts and is very versatile and can be used for a variety of plumbing applications with amazing results

What is the weld hardness in welded pipe?

The answer is entirely dependent on the material/s you are welding. Consult ASME for your specific application.

Demagnetize carbon steel pipe to weld?

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.

How do you calculate number of welding electrodes required for pipe weld?

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 electrode 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 azimpathan_041@yahoo.in 96241 80135

What is the difference between seamless and welded pipes?

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.

Why do they use copper for water pipes?

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 work 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.

Why is copper used for wiring and pipes?

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.

How can you demagnetize a heavy wall pipe for welding?

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 to 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)

What is furnace butt welded pipe?

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.

What is difference between Electric resistance welded pipe with Fusion welded pipe?

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.

Is double submerged arc welded pipe categorized as electric fusion welded pipe?

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.

Will J B weld seal exhaust pipe leaks?

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.

Difference between seamless and welded pipes?

A welded pipe has a visible seam. -That's a little clue about why they call the other kind 'seamless' .

What kind of welding machine do you use to weld your muffler?

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.

What kind of welding rod do you use to weld railway lines?

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 very 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.

Is it ok to weld gi pipe?

Gi weld not recommended . Because of gi coationg will be spoiled out . Puncture will be occur on the pipe weld .

Can you use JB Weld on aluminum?

Yes. I've used it on aluminum as a permanent repair. I'd recommend prepping the surface thoroughly.

Can MS pipes welded with GI pipe?

Very likely to leak, zinc in the GI pipe will be contaiminating the weld and thus you cannot get a good weld.

Can nitrogen be used to purge gas pipes before welding?

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, and 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.

What if galvanised iron pipe joint by welding?

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. Symptons 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.

Can it be used for copper pipe?

I am sorry, but can you PLEASE rephrase your question? Can WHAT be used for copper pipe? When? How? Why?

How much prices for welding pipe per dia inch?

It greatly depends on material cost and the labour cost. In middleeast region, it is around USD 10 / Inch dia for CS welding

How do you stop pipes from bending when 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.

Can liquid weld be used on PVC pipe?

No, it won't stick to most PVC. Oatey's Transition Cement and most epoxies will work IF the PVC is dry.

What method can you use to recover and weld a 6 pipe off the sea bed?

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 offshore engineering and construction, and is usually very expensive because of the specialist vessels and personnel required.

What is the average manhour of pipe weld per inch dia?

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 environmental 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.

Why copper is useful for heater pipes?

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.

What is the difference between seamless and welded pipe fittings?

welded pipe is a pipe made joining using weld metal to make it a pipe..and a seamless is made like moulding

How do you weld MS pipe to GI pipe?

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.

Why is copper not used on service pipes?

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 electrolysis 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.

Can a 8in weldolet be welded on 8in pipe?

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.

What is rigid copper pipe use for?

Mostly used for plumbing inside a house. -Personally, I prefer PEX, easier to install and lasts longer.

Can you weld HDPE pipe?

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.

Can killed carbon steel pipe be welded?

Yes. Argon gas welding is often used for killed steel welding to inhibit the oxidation of the steel.

Can you weld nace pipe with non-nace pipe?

Welding should only be done between similar metals. Installing welded flanges to connect two dissimilar metals would be the preferred method of connection.

Why is filet weld necessary while welding slip on flanges to a pipe end?

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.

What kind of sealers are useful for copper pipe?

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.

How do weld GI pipe to GI pipe?

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.

What are copper pipes used for?

Copper pipes are used to insulate electricity because the electrical current can not pass through the softer of all the metals. The copper pipes can be found in electrical appliances such as television tubes and computer CRT. Around the house, copper tubing can be found in the circuitry of the circuit breaker that is usually located in garage or a shed to a house or an apartment.

What kind of material can used to weld copper pipes?

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 soldering is not ideal.
