Metallurgical Engineers use complex equipments such as electron microscopes, X-ray machines and spectrographs. They use the latest technological and scientific findings in their work. Metallurgical engineers are specialize in one of three areas including chemical metallurgy, physical metallurgy and process metallurgy. Chemical metallurgists focus on the extraction of metals, Physical metallurgists focus on the behaviour of metal under different conditions whereas Process metallurgists are accountable of designing metal parts through casting, welding and soldering etc.
