Welding engineering combines the fundamental principles of materials, mechanical, structural and electrical engineering and adapts them to the development and application of joining technology.

Welding engineering includes many different processes, including various methods of welding, soldering, welding, adhesive bonding, special types of mechanical fasteners, etc. Advances in the technology of these processes enable a wide variety of materials such as metals, ceramics, polymers, composites, and electronics to be joined in ways that maximize reliability and minimize cost.
