Mechanical Technology: Welding and Metalwork includes welding (gas, electric, MIG/MAGS), developments, working with sheet metal and the manufacturing of structures. Welding is a fabrication or sculptural process that joins materials by melting the work pieces and adding a filler material to form a pool of molten material that cools to become a strong joint. While often an industrial process, welding may be performed in many different environments, including open air, under water and in outer space. Metalworking is the process of working with metals to create individual parts, assemblies, or large scale structures. The term covers a wide range of work from large ships and bridges to precise engine parts and delicate jewellery. It includes a correspondingly wide range of skills, processes and tools. Metalworking is a science, art, hobby, industry and trade. Modern metalworking processes can be categorized as forming, cutting, or joining processes. Today's machine shop can create precise and useful work pieces.
