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 ...
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]
A clamp holder or clamp fastener is a piece of laboratory apparatus that is used to secure laboratory clamps, such as extension-type utility clamps, or other attachments to a retort stand or lab frame. [1] The material can be made up of brass, cast iron, stainless steel, aluminium or nickel-plated zinc. [2]
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.
In this way almost all the magnetic flux will be concentrated inside both iron U's creating a close circuit for the magnetic field (because the high permeability of the iron). Having all the flux confined inside the structure, the magnetic flux outside became almost nonexistent. In this configuration we can say the big magnet is OFF.
The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.
