To prevent oxidation and allow the alloy to flow into the fitting capillary action (attraction) and it is best to use a non acid flux and if one knows how to braze they can braze joints with a tensile strength of 87,000 PSI without the use of flux PROVIDING you use the correct rod as per AWS

How do pneumatic tube systems work?
Pneumatic tube systems today are most seen at the drive-through windows of banks. Pneumatic tubes use pressured air to push a sealed object through the system. how do pneumatic truck trailers work?
What machines use pneumatic tube systems?
A variety of automation systems use pneumatic tubes to move material via puffs of air. Bank systems still use them. In the Denver Airport, large pneumatic tubes move aircraft parts around the terminals.
What is use of stay tube in Cochran boiler?
The stay tubes basically hold the boiler together, they are thicker than the ordinary tubes and generally dont need to be replaced as often.
Which valve is the preferred valve to use as flow control valve at the pump discharge 8 inch size ball valve can be used for the same application?
I would use a butterfly valve to set the flow and a pitot tube to measure it. Nexus Valve makes a good one and it is price competetive as well.
Use of draft tube in reaction turbine?
1. To reduce velocity/ kinetic energy of water making exit thereby converting kinetic energy to pressure head allowing turbine to be installed above tail pool level. 2. To create negative suction head. 3. Provide added head.
Can I use acid flux when soldering copper pipe for a water line?
All flux has acid so yes u can as long as u wipe it clean after u solder it will cause Ur joint to turn green
What is the purpose of using soldering flux?
After cleaning copper pipe and fitting, applying flux helps ensure that solder will adhere to pipe and fitting when joint is heated to proper temperature.AnswerIt depends on what type of 'flux' you are talking about? For example, 'electric flux' and 'magnetic flux' exists naturally, and is not 'for' anything in particular, although it can be made use of.
What can you use soldering for?
Use soldering to permanently connect electrical contacts, and also to permanently join copper water pipes without leaks (if you do it right!!)
What is the use of acid in soldering and brazing?
It is used to clean impurities away from the surface to be soldered or brazed. Many times it is included in the flux. The use of acid type of fluxes is actually detrimental to good plumbing , soldering practices because if the flux is not properly cleaned the joint will eat away from the corrosive action of the acid
What am I doing wrong when I can't get the solder to stick when soldering a copper pipe?
Not cleaning the pipe or joint enough, not using flux, or not heating the pipe or joint enough. You use the blue tip of the flame on the joint and the capillary action sucks the solder into the joint. You have to clean the pipe with sandpaper or steel wool, the joints with a fitting brush on the inside, and use a proper flux and solder.
Why would you seem to have a lot of gas leaks lately while soldering joints that might be attributed to using MAPP Gas with Power Flux?
i only use silver solder comes in a flat stick ,and flows effortless on copper and brass without any flux,sounds like your solder is not flowing due to lack of heat using mapp,acetylene is the best but try the silver solder without flux
What do people use to combine copper and tin?
Copper and tin could be melted and combined as an alloy, They can also be fastened together by some form of brazing, like soldering.
Your car heater on back has come unstuck how do you fix it so it will clear again the solder has come off?
You can use a paste flux and heat (as from a soldering gun) to reattach the solder.
Can you use an electric soldering iron on copper pipe and hobby tubing?
Rigid makes an electric soldering tool for soldering when an open flame is impractical like working in a hospital where there is flammable gases or Oxygen present.A regular type soldering iron may not get the fittings hot enough to allow for capillary attraction to draw the alloy into the fitting
How do you sauder a bookcase?
Sauder bookcases are purchased from a store location or an online store. Soldering, however, is more complex as you need to use heating elements, flux, and experience along with other items.
Why does solder no longer have lead in it?
Since question is not clear two answers can be given on the assumption that the question is about dry soldering. Thoroughly clean the part to be soldered, apply flux re-solder the connection. The second answer is normally lead will not be kept on a soldering point. the technician doing soldering has to use lead and flux separately. ================================ There are still solders that contain lead. The European Union prohibited excessive amounts of lead in consumer products (WEEE and RoHS), so there are lead-free solders. But there are industries in which the lead-free solders are not acceptable.
Why is copper used for making soldiering iron?
Copper is used because it is a good conductor of heat and thus more energy efficient. The solder melts at a temperature lower than copper and the soldering iron is controlled to only reach a high enough temperature to melt the solder. There are metals that are more efficient at conducting heat, But considering the melting point of copper, it high availability and relative cost. Copper is by far the obvious choice to use in a soldering iron.
