Welding current regulating device for spot-welding with a fuzzy-transducer for the quantitative detection of the strength of welding splatters

摘要

The appts. includes filters (F1,F2,F3) serving respectively for determn. of the relative variation of the electric resistance (R) of the workpiece, the variation (EB) of the electrode acceleration, and the amplitude (AEB) of the electrode acceleration. The appts. further includes a fuzzy-logic data transmitter (FM) with inputs (R,AEB) from the filters (F1,F3) and a welding current control unit (SF) with inputs (R,EB) and (S) (with the last-named quantity representing the intensity of weld splashes) respectively from the filters (F1,F2) and the data transmitter (FM).
