摘要： An apparatus for controlling resistance welding defines a weld time for series welding as a plurality of (e.g., two) weld periods. In one embodiment, a control (56) successively switches a bidirectional switch (30) in a first polarity during the first weld period so that welding current flows through workpieces of different metals in one direction by passing through a series of welding points of the workpieces. In the second weld period, the control (56) successively switches the bidirectional switch (30) in the reversed polarity so that welding current flows through the workpieces in the other direction so as to compensate for Pertier effect on the welding points. A polarity changing technique is used to minimize welding energy loss in shifting weld periods for better weld quality. In another embodiment thyristors (66, 68) are controlled by a control (76) such that they are fired in the second half cycle of the supply voltage (E) at an angle smaller than the firing angle in the first half cycle.

摘要： A control unit first enters a schedule No. (code) desired by a user for a given workpiece (step B 1 ). The control unit then identifies the entered schedule No. to read set values of various working conditions being managed by that schedule No. from a memory, and sets them into predetermined registers (steps B 2 , B 3 ). Working condition set values in an associated work section are particularly set (step B 4 ). Then, in response to a start signal from an external device or to a start signal input by the user, the control unit executes a single fusing work (steps B 5 , B 6 ). After completion of the single fusing work, the control unit increments a section work point counter by one (step B 7 ). Then, until reaching the set count of the work points defined in that section, the control unit reiterates the fusing work on the subsequent work points in totally the same working conditions as the above (steps B 8 → B 4 to B 7 → B 8 ).
