ABSTRACT:
A method and apparatus for diagnosing various faults during resistance welding based upon electrode position. An electrode positioning bracket is coupled to the electrode. The position of the bracket is measured by means of a linear variable displacement transducer. The position of the bracket is used to determine the electrode position, and in turn, electrode positioning faults, and weld quality.
