Soldering. Desoldering a contact from a wire. Soldering (US: / ˈsɒdərɪŋ /; UK: / ˈsoʊldərɪŋ /) 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 ...
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 ...
Rigid copper is a popular choice for water lines. Rigid or "Hard" copper tubing is generally referred to as "pipe". Copper "piping" is referred to by nominal pipe size, or the inner diameter. It is joined using a solder/sweat, roll grooved, compression, or crimped/pressed connection. Rigid copper, rigid due to the work hardening of the drawing ...
Although lead pipework is now rare, for health reasons, wiping a joint remains the usual way of joining it. Commonly though a joint is to be made by shortening the old lead and installing new copper or plastic piping beyond the joint. These joints are usually made today with a proprietary mechanical joint, sealing onto the soft lead by some ...
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.
The EPA’s website reads that the most common occurrence of lead in a property without lead lines is copper lines with lead solder. Leusman said water in the pipes can be exposed to the lead solder.
