  2. Standard wire gauge - Wikipedia

    en.wikipedia.org/wiki/Standard_wire_gauge

    Standard wire gauge. A standard wire gauge. British Standard Wire Gauge (often abbreviated to Standard Wire Gauge or SWG) is a unit for denoting wire size given by BS 3737:1964 (now withdrawn). It is also known as the Imperial Wire Gauge or British Standard Gauge. Use of SWG sizes has fallen greatly in popularity, but they are still used as a ...

  3. Electrical discharge machining - Wikipedia

    en.wikipedia.org/wiki/Electrical_discharge_machining

    Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). [1] Material is removed from the work piece by a series of rapidly recurring current discharges between two ...

  4. Electrical resistivity and conductivity - Wikipedia

    en.wikipedia.org/wiki/Electrical_resistivity_and...

    Dimension. − −. Electrical resistivity (also called volume resistivity or specific electrical resistance) is a fundamental specific property of a material that measures its electrical resistance or how strongly it resists electric current. A low resistivity indicates a material that readily allows electric current.

  5. American wire gauge - Wikipedia

    en.wikipedia.org/wiki/American_wire_gauge

    American Wire Gauge (AWG) is a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire. Dimensions of the wires are given in ASTM standard B 258. [ 1 ] The cross-sectional area of each gauge is an important factor for ...

  6. IEC 60228 - Wikipedia

    en.wikipedia.org/wiki/IEC_60228

    Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...

  7. Gas metal arc welding - Wikipedia

    en.wikipedia.org/wiki/Gas_metal_arc_welding

    Most models provide the wire at a constant feed rate, but more advanced machines can vary the feed rate in response to the arc length and voltage. Some wire feeders can reach feed rates as high as 30 m/min (1200 in/min), [12] but feed rates for semiautomatic GMAW typically range from 2 to 10 m/min (75 – 400 in/min). [13]

  8. Guy-wire - Wikipedia

    en.wikipedia.org/wiki/Guy-wire

    A sailboat's mast is supported by shrouds (side-to-side) and stays (fore-and-aft) – nautical equivalents of guy wires. A guy-wire, guy-line, guy-rope, down guy, or stay, also called simply a guy, is a tensioned cable designed to add stability to a freestanding structure. They are used commonly for ship masts, radio masts, wind turbines ...

  9. Magnetic field - Wikipedia

    en.wikipedia.org/wiki/Magnetic_field

    A solenoid (electromagnet), a coil of wire with an electric current through it. The shape of the magnetic fields of a permanent magnet and an electromagnet are revealed by the orientation of iron filings sprinkled on pieces of paper. A magnetic field (sometimes called B-field[ 1 ]) is a physical field that describes the magnetic influence on ...
