The constant of proportionality K is called the “gauge factor,” which has been determined on the basis of the metal (alloy) used for the strain gauge. With no load, the resistance of a strain gauge is generally 120 σ. During general strain measurement, the change in the resistance is ...
Sintered metal is a material created by heating metal powder particles below their melting point, causing them to bond together and form a solid object with a desired shape, essentially "sintering" the powder into a solid piece through the application of heat and pressure; this process allows fo...
Metal finishing can be a physical, chemical or mechanical process. In general, metal finishing is used to protect, enhance the appearance of, and/or improve the performance of the product. The term “metal finishing” is actually somewhat of a misnomer, as it encompasses non-metallic surfaces ...
Manual metal arc welding: this is how it works In electrode welding, contact between the rod electrode and workpiece ignites the arc. This creates a short circuit for a fraction of a second between the two poles, meaning that current can then flow. The arc burns between the workpiece and ...
