Which of the following statements is true regarding a compression riveter?

A compression riveter operates by applying a specified amount of pressure to rivets to ensure they are properly set. This controlled application of pressure is critical because it allows for consistent and reliable rivet installation, achieving the desired deformation of the rivet without risking damage to the surrounding materials or over-compression, which could lead to a failure in structural integrity.

The mechanism typically includes a pressure regulator or similar system to ensure that the right amount of force is applied, which varies depending on the rivet type and material. This precision is essential in aerospace applications, where the efficacy of joint integrity can significantly affect safety and performance.

In contrast, the other statements do not reflect the operational characteristics of a compression riveter accurately. For example, while some tools may be manually operated, the concept of "infinite pressure" or not requiring any power source does not hold true, as these factors would compromise the ability to control rivet setting effectively.
