Welding, brazing, and mechanical joining are all methods used to connect two or more pieces of metal. Each method has its own unique advantages and disadvantages, making it suitable for different applications. The choice of method depends on factors such as the materials being joined, the desired strength and durability of the joint, the environmental factors the joint will experience, and the cost and complexity of the process.

Burnishing, a cold working process, offers a multitude of benefits for the aerospace industry. By improving surface finish, increasing hardness, and introducing compressive residual stresses, burnishing enhances the performance and durability of critical components. This article delves into the specific applications of burnishing in engine components, landing gear, bearing surfaces, and fuel systems.

Tube removal is a common challenge regardless of the application. In air cooled exchangers, the layout of the tubes, as well as the outer diameter of the fins, could pose some challenges if using traditional methods. However, there are a few tips to make this process quicker.
