  2. 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.

  3. Solderability - Wikipedia

    en.wikipedia.org/wiki/Solderability

    Both quantitative and qualitative tests for solderability exist. [6] The two most common testing methods are the 'dip and look' method and wetting balance analysis.In both of these tests, the soldered pieces undergo an accelerated aging process before being tested for solderability, to take into consideration the time a component was in storage prior to mounting to final assembly.

  7. 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%.
