摘要： A weld control structure and method for delaying initiating a weld until the voltage of a source of welding energy is at a preselected variable value or a variable preselected number of cycles a source of welding energy have occurred without the voltage reaching the preselected value and providing a fault indication when the weld is initiated as a result of the preselected number of cycles being reached witout the voltage reaching the preselected voltage. The structure includes a voltage checker for checking the voltage in each cycle of a single phase source of electrical welding energy, a counter for counting each cycle of the energy source in which the voltage is checked after a weld is requested, a fault indicator and a central processing unit programmed to initiate a weld only when the voltage of the energy source has reached the preselected value or the counter has reached the preselected count without the voltage reaching the preselected value operably connected to the voltage checker, counter, fault indicator and welder.

The method includes sensing the voltage in each cycle of a single phase welding energy source and initiating a weld when the voltage reaches a predetermined variable value or initiating a weld and energizing a fault indicator when a counter for counting the cycles of the energy source in which the voltage has been checked has reached a preselected variable member of counts without the voltage reaching the preselected value.

摘要： A monitoring and control system for use in conjunction with a pulse type welder which utilizes a computer to calculate the impedance characteristics of a weld and compare these characteristics to a preselected set of characteristics to determine if a quality weld has been made. The system then controls the heat and cool time to increase or decrease the tmeperature of the weld and thus control the size of the weld nugget. The monitoring control system is utilized in conjunction with a standard pulse welding control system, which standard system provides a series of heat impulses followed by a series of cool impulses, this cycle being repeated for a preselected number of cycles. The monitoring and control system senses the voltage and current in the welding load and feeds this data to a computer which, in turn, calculates the impedance of the weld. This calculation is then compared to a predetermined set of standards which are evolved as a result of processing a preselected number of previous welds, and corrections are made to assure the weld quality. If the temperature of the weld has not been sufficiently elevated, the number of impulses in the cool portion of the cycle, and thus the cool time, is reduced until the weld meets the set standards. On the other hand, if the temperature exceeds the standard, the number of heat impulses, and thus the heat time, is reduced.
