US Patent No: 5436422
Resistance welding control method
Abstract
A resistance welding control method capable of reducing generation of spatter to the utmost during consumption of electrodes, thereby obtaining a desired nugget and assuring excellent welding quality and controlling with ease. The resistance welding control method comprises the steps of detecting a primary or secondary voltage when the welding current is supplied to the workpiece, monitoring a resistance value of the workpiece at welding operation with the lapse of time based on the primary or secondary voltage and the welding current which is detected in synchronization with the detection of the primary or secondary voltage so that an expansion tendency of electrode tip diameter is recognized and stored as first data in a computer of the resistance welding apparatus and at the same time a spatter generation condition at welding operation is learned and stored as second data in the computer, obtaining a welding current pattern based on the first and second stored data and statistically processed data stored in the computer, and controlling resistance welding by the welding current pattern so as to obtain a desired nugget while reducing generation of spatter to the utmost even in the consumption of electrodes.
