摘要： A multivariable process monitor and method of monitoring a resistance spot welding process to yield instantaneous information on weld quality during the weld cycle. Sensors on the machine measure welding input variables and workpiece response variables and provide signals to a microcomputer system. A simplified analytical model of the spot welding process is incorporated in the microcomputer and is the reference for the weld quality logic that accepts or rejects the weld. Faulty welds are diagnosed and the reason displayed.

摘要： A conventional fusible element is combined with exothermic reactive material such as PETN or a ribbon of aluminum-palladium to supply quickly released chemical energy for fast circuit interruption where the circuit-derived electrical energy available for interruption is low. An arc quenching substance preferably surrounds the fusible element. The exothermic reaction is initiated thermally or by supplementary electrical energy from a trigger circuit.
