  2. Brazing - Wikipedia

    en.wikipedia.org/wiki/Brazing

    Brazing practice. Brazing is a metal-joining process in which two or more metal items are joined by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal. Brazing differs from welding in that it does not involve melting the work

  3. Copper tubing - Wikipedia

    en.wikipedia.org/wiki/Copper_tubing

    Solder fittings are smooth and easily slip onto the end of a tubing section. The joint is then heated using a torch, and the solder is melted into the connection. When the solder cools, it forms a very strong bond that can last for decades. Solder-connected rigid copper is the most popular choice for water supply lines in modern buildings.

  4. Soldering - Wikipedia

    en.wikipedia.org/wiki/Soldering

    Soldering and brazing are thought to have originated very early in the history of metal-working, probably before 4000 BC. [2] Sumerian swords from c. 3000 BC were assembled using hard soldering. Soldering was historically used to make jewelry, cookware and cooking tools, assembling stained glass, as well as other uses.

  6. Piping and plumbing fitting - Wikipedia

    en.wikipedia.org/wiki/Piping_and_plumbing_fitting

    The welding of metals differs from soldering and brazing in that the joint is made without adding a lower-melting-point material (e.g. solder); instead, the pipe or tubing material is partially melted, and the fitting and piping are directly fused. This generally requires piping and fitting to be the same (or compatible) material.

  7. Pipefitter - Wikipedia

    en.wikipedia.org/wiki/Pipefitter

    Pipe fitters plan and test piping and tubing layouts; cut, bend or fabricate pipe or tubing segments; and join those segments by threading them, using lead joints, welding, brazing, cementing, or soldering them together. They install manual, pneumatic, hydraulic and electric valves in pipes to control the flow through the pipes or tubes.

  8. Flux (metallurgy) - Wikipedia

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

    For successful soldering and brazing, the oxide layer has to be removed from both the surfaces of the materials and the surface of the filler metal preform; the exposed surfaces also have to be protected against oxidation during heating. Flux-coated preforms can also be used to eliminate flux residue entirely from the soldering process. [14]

  9. Pin brazing - Wikipedia

    en.wikipedia.org/wiki/Pin_brazing

    Pin brazing is a metallurgically safe [citation needed] method of making electrical connections [1] to steel and ductile iron pipelines [citation needed] as well as other metallic structures, [2] which are to be cathodically protected or electrically earthed.
