2. Magnetic switchable device - Wikipedia

   en.wikipedia.org/wiki/Magnetic_switchable_device

   A magnetic switchable device (often called a magnetic base) is a magnetic fixture that uses one or more permanent magnets in a configuration that allows the external field to be turned on or off. They are used in many applications including optics , metalworking , lifting , and robotics, to attach items to metal surfaces in a secure but ...

3. Magnetic pulse welding - Wikipedia

   en.wikipedia.org/wiki/Magnetic_pulse_welding

   Magnetic pulse welding (MPW) is a solid state welding process that uses magnetic forces to weld two workpieces together. The welding mechanism is most similar to that of explosion welding. [1] Magnetic pulse welding started [clarification needed] in the early 1970s, when the automotive industry began to use solid state welding. [citation needed]

4. Clamp (tool) - Wikipedia

   Upper row: F-clamp or bar clamp, one-handed bar clamp ("Quick Grip"), wooden handscrew; Lower row: spring clamp, C-clamp (G-clamp ), wooden cam clamp. A clamp is a fastening device used to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure.

5. Shielded metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Shielded_metal_arc_welding

   As welding progresses and the electrode melts, the welder must periodically stop welding to remove the remaining electrode stub and insert a new electrode into the electrode holder. This activity, combined with chipping away the slag, reduces the amount of time that the welder can spend laying the weld, making SMAW one of the least efficient ...

6. Arc blow - Wikipedia

   en.wikipedia.org/wiki/Arc_blow

   Magnetic arc blow is known to begin at field densities as low as 10 gauss and becomes severe at densities of, equal to or greater than, 40 gauss; it is directional and can be classified as forward or backward moving along the joint, but can occasionally occur to the sides depending on the orientation of the poles to the workpiece.

7. Chuck (engineering) - Wikipedia

   (The axial movement of cones is not mandatory, however; a split bushing squeezed radially with a linear force—e.g., set screw, solenoid, spring clamp, pneumatic or hydraulic cylinder—achieves the same principle without the cones; but concentricity can only be had to the extent that the bushing's diameters are perfect for the particular ...
