Abstract: A method for determining the cooling rate of a weld, comprising locating at least one non-consumable thermal sensor at a predetermined location from a weld pool generated during an active welding process, wherein the thermal sensor is located within the same plane of travel as a welding device creating the weld pool; determining the travel speed of the welding device; using the at least one non-consumable thermal sensor to gather temperature data from the weld pool; and determining the time interval between when the weld pool has a first measured temperature and when the weld pool has a second measured temperature that is less than the first measured temperature, wherein the determined time interval represents the cooling rate of the weld.
