IPC: B23K11/24
Filed: 1980-01-17
Abstract: PURPOSE: To make it possible to judge welding condition with a high accuracy even for thin materials, by obtaining ultrasonic transmission quantity by installing an ultrasonic oscillator for transmitting and receiving to the counter electrode, and by comparing the point of inflection and maximum point obtained from the signal with the reference signal.  
     CONSTITUTION: The pulse signal is supplied from oscillation circuit 16 to ultrasonic oscillator for transmitting 13 at the same time when welding is started. This ultrasonic wave is sent to ultrasonic oscillator for receiving 14 through material 12 to be welded. This signal is input into storage circuit 21 through gate circuit, filter 19 and amplifier circuit 20. Based on the signal corresponding to the variation in stored ultrasonic transmission quantity, the point of inflection is detected at point of inflection detecting circuit 22 and the maximum value is detected at maximum value detecting circuit 23. Both the detected values are input into operation circuit 24 and difference between the point of inflection and maximum value is found. This difference is sent to comparator 25 and compared with the set value, and, when the sent value is larger than the set value, it is displayed on display circuit 27 that welding condition is good. When the sent value is smaller than the set value, it is displayed that the welding condition is not good.
