Welding engineering employs science and engineering in joining components made of metals, ceramics, plastics and other materials. Welding engineering includes design of the joints to be welded, development of the detailed joining procedures to be used, selection of the materials incorporated in the joint, joint inspection and quality control for the final product. Welding engineering can also involve research in these areas, such as developing new welding processes or procedures for new materials. Welding engineers work with design engineers to develop efficient welding designs and fabrication procedures.
