What type of joint is primarily used by plumbers for creating a strong connection?

Plumbers often rely on soldered joints to create strong, durable connections in piping systems. Soldering involves melting a filler metal, which is generally an alloy with a lower melting point than that of the metal being joined, to bond two metal components together. This process not only provides a tight seal that can withstand pressures found in plumbing systems but also prevents leaks, which are critical in any plumbing installation.

Soldered joints are especially common in copper piping, where the application of heat can lead to a reliable bond that ensures the integrity of the system. The flexibility and strength of a soldered joint make it suitable for various applications across residential and commercial plumbing, cementing its status as a preferred choice for creating robust connections.
