What makes a good conductor? In a conductor, the outer electrons of the atom are loosely bound and can freely move through the material when an electric charge is applied. In general, the best electrical conductors are metals. Metals tend to have electrons in the outer layer of their atoms that are freely shared. How […]

What is ceramic backing in welding?
What is ceramic backing in welding? Ceramic backing strips can be used with every weldable material to reduce oxidation and prevent hydrogen inclusion, by providing a heat-reflecting, weld-supporting surface against which to deposit the welding consumable. Gas release gaps reduce porosity by preventing gas-entrapment. Why backing strip is used in welding? A backing (strip) is […]
