2. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   Soldering (US: / ˈ s ɒ d ər ɪ ŋ /; UK: / ˈ s oʊ l d ər ɪ ŋ /) is a process of joining two metal surfaces together using a filler metal called solder. The soldering process involves heating the surfaces to be joined and melting the solder, which is then allowed to cool and solidify, creating a strong and durable joint.

3. Point-to-point construction - Wikipedia

   en.wikipedia.org/wiki/Point-to-point_construction

   The crucial invention was to apply soldering to electrical assembly. In soldering, an alloy of tin and lead (and/or other metals), known as solder, is melted and adheres to other, nonmolten metals, such as copper or tinned steel. Solder makes a strong electrical and mechanical connection.

4. Soldering iron - Wikipedia

   en.wikipedia.org/wiki/Soldering_iron

   Soldering irons are designed to reach a temperature range of 200 to 480 °C (392 to 896 °F). [1] Soldering irons are most often used for installation, repairs, and limited production work in electronics assembly. High-volume production lines use other soldering methods. [2] Large irons may be used for soldering joints in sheet metal objects.

5. Solder alloys - Wikipedia

   en.wikipedia.org/wiki/Solder_alloys

   Soldering copper pipes using a propane torch and a lead-free solder. Solder is a metallic material that is used to connect metal workpieces. The choice of specific solder alloys depends on their melting point, chemical reactivity, mechanical properties, toxicity, and other properties.

6. Filler metal - Wikipedia

   en.wikipedia.org/wiki/Filler_metal

   Brazing and hard soldering use a higher temperature filler that melts at a temperature which may approach that of the base metal, and which may form a eutectic alloy with the base metal. Filler alloys have a lower melting point than the base metal, so that the joint may be made by bringing the whole assembly up to temperature without everything ...

7. Dip soldering - Wikipedia

   en.wikipedia.org/wiki/Dip_soldering

   Dip soldering is used for both through-hole printed circuit assemblies, and surface mount. It is one of the cheapest methods to solder and is extensively used in the small scale industries of developing countries . Dip soldering is a manual equivalent of automated wave soldering. The apparatus required is just a small tank containing molten solder.

8. Conservation and restoration of iron and steel objects

   en.wikipedia.org/wiki/Conservation_and...

   The treatment report will indicate what type of structural treatment should be used. If the item is missing hardware it can be replaced by adding matching or similar screws and rivets. Adhesives, soldering, and welding can be used to repair a damaged structure. Protective coatings. Protective coatings can be good options for iron and steel objects.

9. Whisker (metallurgy) - Wikipedia

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

   Metal whiskering is a phenomenon that occurs in electrical devices when metals form long whisker-like projections over time. Tin whiskers were noticed and documented in the vacuum tube era of electronics early in the 20th century in equipment that used pure, or almost pure, tin solder in their production.
