Many mechanical engineers work in the areas of air-conditioning and refrigeration, automotives, manufacturing, welding, and robotics. They designed the robotically controlled braces that people with disabilities use to walk. For more information, contact the American Society of Mechanical Engineers . Metallurgy and Materials Engineering Metallurgical and materials engineers extract, process, refine, combine, and manufacture natural substances to create new materials that are stronger and resist corrosion.
Metallurgical engineers work with metal only.
For more information, contact the Society for Mining, Metallurgy, and Exploration . Mineral and Mining Engineering Mineral and mining engineers locate, remove, and appraise minerals they find in the earth. Mining engineers lay out the mines, supervise their construction, create a materials transportation system, and return the area to its natural state upon mining completion. Mineral and mining engineers need to know how to mine the natural wealth underground without destroying the land above or disrupting the people that live on it.
