  2. Model engineering - Wikipedia

    en.wikipedia.org/wiki/Model_engineering

    A typical beginner's project. Model engineering is the pursuit of constructing proportionally-scaled miniature working representations of full-sized machines. It is a branch of metalworking with a strong emphasis on artisanry, as opposed to mass production. While now mainly a hobby, in the past it also had commercial and industrial purpose.

  3. Metalworking - Wikipedia

    en.wikipedia.org/wiki/Metalworking

    Metalworking is the process of shaping and reshaping metals in order to create useful objects, parts, assemblies, and large scale structures. As a term, it covers a wide and diverse range of processes, skills, and tools for producing objects on every scale: from huge ships, buildings, and bridges, down to precise engine parts and delicate ...

  4. Shielded metal arc welding - Wikipedia

    en.wikipedia.org/wiki/Shielded_metal_arc_welding

    Shielded metal arc welding. Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding[1] or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld. An electric current, in the form of either alternating current or ...

  5. Metalsmith - Wikipedia

    en.wikipedia.org/wiki/Metalsmith

    Metalsmith. A metalsmith or simply smith is a craftsperson fashioning useful items (for example, tools, kitchenware, tableware, jewelry, armor and weapons) out of various metals. [1] Smithing is one of the oldest metalworking occupations. Shaping metal with a hammer (forging) is the archetypical component of smithing.

  6. Metal spinning - Wikipedia

    en.wikipedia.org/wiki/Metal_spinning

    Metal spinning, also known as spin forming or spinning or metal turning most commonly, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. [1] Spinning can be performed by hand or by a CNC lathe. The metal spinning trade is one that dates back to antiquity and was a ...

  7. Arc welding - Wikipedia

    en.wikipedia.org/wiki/Arc_welding

    Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals, when cool, result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base material to melt ...

  8. Raising (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Raising_(metalworking)

    Raising (metalworking) Raising is a metalworking technique whereby sheet metal is formed over a solid object by repeated "courses" of hammering and annealing. A sheet metal worker is often required to raise, or bump, the work into form from the flat metal by means of a raising hammer and raising block. The raising block is made from substance ...

  9. Forming (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Forming_(metalworking)

    Forming (metalworking) In metalworking, forming is the fashioning of metal parts and objects through mechanical deformation; the workpiece is reshaped without adding or removing material, and its mass remains unchanged. [1] Forming operates on the materials science principle of plastic deformation, where the physical shape of a material is ...
