Methods are disclosed for rating a welding electrode and/or for ranking two or more electrodes with respect to gas tracking effects in gas shielded flux cored arc welding processes. The methods involve performing a standardized welding process using an electrode of interest to create a test weld on a workpiece with a linearly varying contact to work distance in the process, measuring a distance from the beginning of the weld to a point at which gas tracking is first observed, and rating an electrode or ranking several electrodes according to the measured distance.
