Research, design, development into aeronautical and astronautical engineering - Aerospace engineering, Deals with the study and application of electricity, electronics and electromagnetism - Electrical engineering, Uses physics and materials for analysis, design and manufacturing of mechanical systems - Mechanical engineering, Uses engineering and science to solve healthcare problems - Biomedical engineering (BME), Applies chemistry, physics, microbiology and biochemistry with maths to make chemicals into useful forms - Chemical engineering, Brings together electrical engineering with computer science to enhance telecommunication systems - Communications engineering, design, manufacture and operation of auto vehicles - Automotive engineering, Uses heat to from gas for welding - MIG welding, Metal Inert Gas - What does MIG stand for?, Gas welding. The flame is produced by oxygen and acetylene.  - Oxy acetylene welding, Used to join sheet metal together. Uses a transformer and two electrodes. - Spot welding, Metal being heated and shaped by deformation. - Forging, Pouring or injecting a liquid metal into a mould. It cools and solidifies.  - Casting, A process used to cut straight lines on a range of materials. An upper and lower blade are forced past each other to cut.  - Shearing, Printed Circuit Board - PCB, Surface Mount Technology - SMT, Production to make a prototype. Higher costs. Unique product. - One off production, A certain quantity of identical products.  - Batch production, Used to produce very large quantities of a product.  - Mass production, Constant production of products. Costs per unit are cheaper than if produced in other quantities.  - Continuous flow, Mechanical devices that can be programmed to carry out jobs - Robots, Computer Numerically Controlled - CNC, Computer aided manufacture - CAM, Computer aided design - CAD, A material that can have one or more of its properties changed in a controlled manner by an external stimulus. - SMART material, Return to their original shape after heating and deformation. - Shape memory alloy, Change colour when the heat changes.  - Electrochromatic, Can generate electric charge when squeezed or pressed - Piezoelectric actuator/transducer, A material that can absorb large amounts of energy when crushed, allows the transfer of heat energy easily, recyclable. - Metallic foam, Just in time - JIT,
