Name a common structural repair technique used in aviation.

Riveting is a common structural repair technique used in aviation due to its effectiveness in joining metal components while maintaining the integrity of the structure. This method involves using metallic fasteners, known as rivets, to create permanent, secure joints. Riveting is particularly advantageous in aircraft construction and repairs because it can be performed quickly and does not require high-temperature processes that could weaken the surrounding materials.

The use of rivets allows for efficient assembly and disassembly of aircraft components, which is crucial for maintenance and repairs. Additionally, riveting provides a lightweight yet strong connection, which is essential for maintaining the overall performance and fuel efficiency of the aircraft.

In contrast, welding, while also a joining technique, involves melting materials together, which can lead to heat distortion and potential weaknesses in the materials if not done properly. Machining is a subtractive process that removes material to achieve desired dimensions, typically used for creating precise parts rather than repairs. Coating, while important for protection against corrosion and wear, does not serve as a structural joining technique.
