2. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   Soldering is used in plumbing, electronics, and metalwork from flashing to jewelry and musical instruments. Soldering provides reasonably permanent but reversible connections between copper pipes in plumbing systems as well as joints in sheet metal objects such as food cans, roof flashing, rain gutters and automobile radiators.

3. Wave soldering - Wikipedia

   en.wikipedia.org/wiki/Wave_soldering

   Wave soldering is a bulk soldering process used for the manufacturing of printed circuit boards. The circuit board is passed over a pan of molten solder in which a pump produces an upwelling of solder that looks like a standing wave. As the circuit board makes contact with this wave, the components become soldered to the board.

4. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   Any material permitted by the plumbing, health, or building code (as applicable) may be used, but it must be compatible with the other materials in the system, the fluids being transported, and the temperature and pressure inside (and outside) the system. Brass or bronze fittings are common in copper piping and plumbing systems.

5. Solder alloys - Wikipedia

   en.wikipedia.org/wiki/Solder_alloys

   Sn30, UNS L54280, crude solder for construction plumbing works, flame-melted, good for machine and torch soldering. [54] Used for soldering car engine radiators. Used for machine, dip and hand soldering of plumbing fixtures and fittings. Superior body solder. [52] Pb 68 Sn 32: 253: Pb: No "Plumber solder", for construction plumbing works [28 ...

6. Trisodium phosphate - Wikipedia

   en.wikipedia.org/wiki/Trisodium_phosphate

   In the U.S., trisodium phosphate is an approved flux for use in hard soldering joints in medical-grade copper plumbing. The flux is applied as a concentrated water solution and dissolves copper oxides at the temperature used in copper brazing. Residues are water-soluble and can be rinsed out before plumbing is put into service.

7. Flux (metallurgy) - Wikipedia

   en.wikipedia.org/wiki/Flux_(metallurgy)

   Rosin used as flux for soldering A flux pen used for electronics rework Multicore solder containing flux Wire freshly coated with solder, held above molten rosin flux. In metallurgy, a flux is a chemical reducing agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time.

9. Wiped joint - Wikipedia

   en.wikipedia.org/wiki/Wiped_joint

   Wiped joints were used for centuries to install water plumbing and similar joints can be seen in Roman plumbing. [3] As the wiping technique allowed a great deal of on-site flexibility for the style and dimensions of the work produced, this meant that plumbers needed few parts other than pipe, lead sheet and solder.
