ABSTRACT:
A method for monitoring and regulating electrical resistance welding by comparing the actual values obtained by integrating measured values of the welding electrodes with desired valued limits obtained by test welding operations in the form of voltage and current parameters. These parameters are integrated in accordance with the formula ##EQU1## WHEREIN Y IS OTHER THAN UNITY AND IS SELECTED SO THAT THE INFLUENCE OF THE RESISTANCE R on the actual, measured value is at least equivalent to the influence of the current I and/or the welding time t, in the above formula, on the measured value. The resultant weld value is then fed to a comparison circuit which contains the upper and lower limits obtained by the test welding. If these limits are exceeded the power to the welding apparatus is automatically disconnected.
