ABSTRACT:
A method for monitoring a resistance welding process carried out on a stack of metal workpieces (1) clamped between two electrodes (2a,2b) of a clamp (3), and a device therefor. According to the method, the electrodes (2a,2b) are subjected to a clamping force (F) and a voltage (V(t)) enabling a current (I(t)) to flow through the stack of metal workpieces (1). The monitoring method further includes at least one step of analysing the clamping force (F) by comparison with a model from a prior learning process. The result of the analysis of each step is taken into account by a decision-making matrix to generate a correction and/or control signal intended for the welding process.
