Method and system for dual control of resistance welding |
摘要 |
A method and system for controlling resistance welding whereby the preferred quality of resistance welding can be ensured automatically during the welding process by controlling the electrode pressure so that the electrode resistance changes in accordance with a reference resistance curve, or by additionally controlling the electrode voltage so that the electrode voltage changes in accordance with a reference voltage curve. The system according to the present invention comprises an electrode voltage sensor, an electrode current sensor, a reference resistance generator, a reference voltage generator, a differential amplifier, a pressure control device, a current controller and so on.
