What is the process of fusing two or more components to form a single part?

The process of fusing two or more components to create a single part is known as joining. This term encompasses various techniques such as welding, soldering, and adhesive bonding, which are used to combine materials and ensure structural integrity. Joining is fundamental in engineering and manufacturing, as it allows for the assembly of complex structures from simpler parts, enhancing versatility and design possibilities.

In contrast, forming refers to shaping materials without removing any material, often through processes such as bending or molding. Shaping might involve cutting or carving materials into a desired form but does not inherently imply combining components. Finishing involves surface treatments and processes that enhance the appearance or durability of a final product, but does not involve the primary alteration of the structural composition through fusing. Therefore, the term that best captures the essence of combining multiple components into a cohesive whole is joining.
