Is it recommended to assemble joints more than three hours ahead of soldering?

When it comes to soldering in pipe fitting, the timing of assembly is crucial for achieving a proper joint. Assembled joints should not be left un-soldered for an extended period, particularly more than three hours, as this can allow moisture and contaminants to accumulate, which adversely affects the soldering process.

Soldering requires clean, dry surfaces to create proper adhesion. If joints are assembled ahead of time and left unattended, they may oxidize or accumulate dust and debris. This can lead to weak or leaky joints once soldered, as the solder may not flow correctly or create a strong bond.

In many cases, it is best to assemble joints and solder them soon after, ensuring that all surfaces remain clean and free of contaminants. This practice ensures that the solder adheres properly and the joint remains strong and leak-free. Therefore, waiting more than three hours to solder assembled joints is not recommended.
