What is a common method for joining sections of boiler tubing?

Welding is the most common method for joining sections of boiler tubing due to the strong, permanent bonds it creates. In boiler construction, where strength and durability are paramount, welding ensures that the joint can withstand high temperatures and pressures typically associated with boiler operation. It allows for seamless connections that minimize the potential for leaks, which is critical in maintaining the efficiency and safety of the boiler system.

Other methods such as screwing or clamping can create joints, but they do not provide the same level of strength or reliability under the intense conditions found in a boiler. Additionally, bonding with adhesives is generally not suitable for high-stress applications like boiler tubing, as adhesives may not withstand the harsh thermal and pressure conditions. Therefore, welding is the industry-standard practice for ensuring the integrity and safety of boiler systems.
