Soldering without flux is possible, but using flux makes the process easier and helps create a stronger bond between the materials being soldered.
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
Flux is used to keep metals from oxidizing. Solder will not bond well with copper-oxides which are formed when copper is exposed to high temperatures (ie a soldering iron) the flux prevents the oxidation. If you were to solder without flux the solder joint would be weak and possibly completely nonconductive.
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.
Soldering iron, solder, flux
Yes, once or twice using flux but only with prototype boards.
When circuit boards are assembled, the parts are soldered on. In order for the solder to make a good connection to the parts and to the board, a substance called flux is mixed into the solder. It removes oxidation and cleans up the surfaces of the different parts so that the solder can stick to them. After the board is assembled, there is still flux on the board. Flux remover dissolves the flux and washes it away.
Plumbers use flux to help clean and prepare surfaces for soldering. Flux removes oxidation and contaminants from the surface, allowing for a stronger bond between the pipes and solder. Additionally, flux helps the solder flow evenly and smoothly, ensuring a proper seal.
The majority of boat props are aluminum. You can't solder it, it has to be welded or heli arced.
flux acts as a wetting agent in the soldering process, reducing the surface tension of the molten solder and causing it to better wet out the parts to be joined.
Yes, flux is a material commonly used in soldering to clean and prepare the metal surfaces being joined. It helps remove any oxide layers, promotes better wetting of the solder to the surface, and enhances the overall soldering process by ensuring a strong bond between the materials.
Flux is used to help solder stick to metal by promoting adhesion and reducing oxidation on the metal surface. It helps clean the surface, create a strong bond, and improve the flow of the solder.
Solder comes in 2 basic varieties, solid and rosin-core. Simple rosin-core solder is a tube of low-melting-point metal with flux filling the single core down the center. Multicore solder has multiple hollows in it, each filled with flux.
