Abstract
PURPOSE: To make spot welding uniform and improve the quality, by detecting the acoustic emission signal at the welding time and by comparing the cumulative value of this signal with the set value to control the welding current.
CONSTITUTION: The acoustic emission signal is detected at the welding time and is converted to an electric signal through piezoelectric element 3. This signal is input to microcomputer 20 through filter circuit 4, amplifier 5, integrator 6, and A/D converter 7 and is accumulated. This cumulative value is compared with the set value given by digital switch 18. The set value of digital switch 12 is taken into computer 20 to operate the welding current, and it is output through D/A converter 22 and is given as the designated value of the thyristor ignition pulse setting circuit of timer 19. If the input value to computer 20 is larger than the set value, the control signal of gate 21 is made low-level to cut power supply.
