Mechanical joining is a crucial process in various industries, including aerospace, automotive, and heavy machinery. It’s used to create a leak-free seal between a tube and a fixed container by expanding the outer diameter of the tube into a series of grooves. This cold working process offers significant sustainability advantages over traditional methods like welding and brazing.

Mechanical joining is the process of joining a tube to a fixed container, like a flange or fitting. Widely used in applications such as hydraulic fittings, transmission blocks, and fluid lines, it offers a cost-effective alternative to welding or brazing.

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.
