2. Soldering - Wikipedia

   en.wikipedia.org/wiki/Soldering

   soft soldering, which originally used a tin-lead alloy as the filler metal; silver soldering, which uses an alloy containing silver; brazing which uses a brass alloy for the filler; The alloy of the filler metal for each type of soldering can be adjusted to modify the melting temperature of the filler.

3. 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. Hence a wide range of solder alloys exist, and only major ...

4. Solder - Wikipedia

   en.wikipedia.org/wiki/Solder

   In the US, manufacturers may receive tax benefits by reducing the use of lead-based solder. Lead-free solders in commercial use may contain tin, copper, silver, bismuth, indium, zinc, antimony, and traces of other metals. Most lead-free replacements for conventional 60/40 and 63/37 Sn-Pb solder have melting points from 50 to 200 °C higher, [17 ...

5. Flux (metallurgy) - Wikipedia

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

   For example, tin-lead solder [5] attaches very well to copper metal, but poorly to its oxides, which form quickly at soldering temperatures. By preventing the formation of metal oxides, flux enables the solder to adhere to the clean metal surface, rather than forming beads, as it would on an oxidized surface.

6. Wiped joint - Wikipedia

   en.wikipedia.org/wiki/Wiped_joint

   The solder grade used for leadworking is plumber's solder (80% lead / 20% tin). [i] Although this is thought of as a high melting point solder amongst lead-tin solders, the solidus is relatively constant for all of these solders and it is the liquidus which climbs from the eutectic point at Sn 63% / Pb 37%.

7. Lead burning - Wikipedia

   en.wikipedia.org/wiki/Lead_burning

   Neither is a flux used. [2] Soldering, by contrast, uses a solder alloy that is some compatible alloy showing eutectic behaviour. This gives a melting point lower than the base metal, allowing a soldering process rather than welding. A filler rod may be needed for some welds, if there is no convenient way to form sufficient close overlap at a ...
