摘要：Device for determining the quality of pressure welding and fusion weldingprocesses, especially resistance welding processes and/or the quality of the weldingjoints produced, comprises a stream determination unit for determining the stream whichflows through the welding point or which is correlated with the power production on thewelding point, an evaluation unit connected to the stream determination unit, and acorrelation unit. An Independent claim is also included for a process for determining thequality of pressure welding and fusion welding processes, especially resistance weldingprocesses and/or the quality of the welding joints produced. Preferred Features: Thecorrelation unit is a neuronal network, a band pass filter assigned to frequency regions ora Fourier analysis device.
