[ad_1] Magnetic flux loss tests steel structures for metal loss due to corrosion. A magnetized structure is tested for magnetic field leaks, indicating areas of corrosion. Magnetic flux dispersion tools detect damage in pipelines by traveling inside them and collecting real-time data. The device consists of a magnetizer and electronic can with sensors to detect […]
[ad_1] Flux Core Arc Welding (FCAW) is a welding process that uses a flux-filled consumable hollow electrode. It can use external shielding gas or rely on the flux content of the electrode. FCAW has advantages over shielded metal arc welding, including high welding speeds and less pre-cleaning. FCAW machines work with constant voltage or current […]
[ad_1] The strength of a magnetic field is measured by magnetic flux density. Electrically charged particles are deflected in magnetic fields. Magnetic fields are created by electric currents. The Earth’s magnetic field is caused by a rotating molten iron core. A compass exploits the phenomenon of weaker magnets lining up with stronger magnets. The measure […]
[ad_1] Heat flux is the transfer of heat energy from a hot area to a cold area, occurring due to temperature differences between objects. Heat flow relies on conduction, convection, and radiation, and is subject to the laws of thermodynamics. The law of cooling states that the rate of heat loss from a body is […]
[ad_1] Flux wire is used in flux cored arc welding (FCAW) as an electrode with a flux core to join two pieces of metal together. There are two types of flux wire: gas shielded and self shielded. The type used depends on the thickness of the metals and the location of the welding. Flux wire […]
[ad_1] Magnetic flux is the amount of magnetic field that penetrates an area perpendicular to it. Gauss’s law states that for a closed surface, the magnetic flux is always zero, and Faraday’s law states that a change in magnetic flux will create a voltage. Materials vary in their reactions to magnetic fields, and the strength […]
[ad_1] Heat flux is the flow of thermal energy from a high to low potential. It occurs through conduction and convection and is measured by temperature differences. Heat flows by diffusion in fluids and by vibrations in solids. Sensible heat flux is due to temperature differences, while latent heat flux is due to phase changes. […]
