Abstract
An ultrasonic welding diagnostic method includes: applying a pressing force to an object to be joined so as to generate a surface pressure on a joint surface of the object to be joined; inputting ultrasonic waves to the joint surface; detecting an elastic wave propagating through the object to be joined by at least one sensor at a plurality of different positions; analyzing a signal detected by the sensor to generate an envelope of the signal and calculating information about the envelope; and determining a joint state on the joint surface based on the calculation result of the information.
