Thermal conductivity is one of the physical properties of the metal. For a welding engineer this is an important property to know and understand about the metal they intend to use for welding. Metals are a good heat conductors and they transmit (welding) heat away from the heat source, some metals conduct heat much faster than the other; for example, Aluminum and Copper conduct heat much faster than steel. This difference in thermal conductivity explains the varying degree of weldability and use of low heat welding process for Aluminum and Copper and their alloys.
