What does “sweating” refer to in soldering?

• A. The method of applying heat to pipes
• B. The process of applying solder to joints using heat
• C. The cooling down period after soldering
• D. The technique of smoothing out solder after application

Answer: (B)

The term "sweating" in soldering specifically refers to the process of applying solder to joints using heat. In this context, it involves heating the joint area of the pipe and fitting until the temperature is sufficient for the solder to melt and flow into the joint. The solder is drawn into the space between the pipe and the fitting by capillary action, which is essential for creating a watertight seal. This precise definition highlights the importance of controlling temperature and ensuring that the solder material is adequately melted to ensure proper adhesion and integrity of the joint. The technique requires skill and attention to detail to avoid overheating or insufficient heating, which can result in a poor bond. Understanding this process is fundamental for effective soldering and ensuring strong connections in pipefitting work.
