Title: Resistance spot welding method and conducting device for welding current
Inventor: KATOU MASAHIRO
IPC: B23K11/25
Filed: 1982-05-13
Abstract: PURPOSE:To perform prescribed spot welding of materials to be welded without generation of harmful phenomena such as explosive scattering, by using the 1st gentle upslope current and the 2nd upslope current of a high rising rate to be changed over smoothly in the stage of spot welding of steel plates having insulating films. CONSTITUTION:A selector 2 selects the current for initial conduction in accordance with the command for starting current conduction from a sequence controller 1 and transmits the signal from the 1st upslope circuit 3 to a current controller 4. The welding current having a small initial value and a low rising rate is flowed by the circuit 3 to break down the insulating films of materials 7 to be welded gradually with the extremely small current, thereby making a minute passage for the current. The circuit is then changed over to the 2nd upslope circuit 8 with the selector 2 so that the current is increased quickly up to the current value of the current conduction in the late period at the current rising rate of a slightly sharp angle of inclination with the current at the point of the time when the 1st upslope is selected as an initial value. The selector 2 is automatically changed over to the current conduction in the late period upon completion of the conduction of the initial current by the above-mentioned two-stages of the upslope so as to flow the welding current of the specified value necessary for formation of nugget.

Filed: 1985-04-17
Abstract: PURPOSE:To enhance the operating efficiency by reducing a DC current to the intermittent limit of a DC reactor when a commutation failure occurs, then waiting the self-recovery of an inverter, then increasing a current,and returning to the normal operation, thereby avoiding an unnecessary trip. CONSTITUTION:A comparator 15 compares an inverter input current applied through a current detector 12 with an inverter output current applied through a current detector 14 to detect the commutation failure in a power inverter 3. When a timer 16 receives the output of the commutation failure from the comparator 16, it operates a limiter 6, and generates a signal for limiting the current command value from a voltage regulator 5 for the prescribed time by operating the limiter 6. Accordingly, when the failure occurs, the current command value is reduced by the output from the timer 6, the output DC current is reduced to its interrupting limit value to continue the operation. After the self-recovery enabling time of the inverter, the inverter is returned to the normal operation.
