ABSTRACT:
To measure the relative power during a welding process, a position sensitive transducer is attached to a welding electrode to submit a signal in response to electrode motion. An accelerometer, carried on an axle of an electrode roll for a Soudronics pulse type resistance welder, will emit a signal indicative of the quality of the weld. The accelerometer measures the forging taking place during welding by means of its position sensitivity and the amount of forging has been found to be a function of the characteristics of the weld.
