Abstract
According to one embodiment, a control method includes setting a transmission angle of an ultrasonic wave to a standard angle. The control method further includes transmitting an ultrasonic wave at the set transmission angle and detecting an intensity of a reflected wave from an object. The control method further includes calculating a tilt angle based on a gradient of the intensity. The tilt angle indicates a tilt of the object. The control method further includes resetting the transmission angle based on the tilt angle.
Claims24
A weld inspection method, comprising:
- transmitting an ultrasonic wave to a weld portion at a transmission angle;
- detecting an intensity of a reflected wave from the weld portion at a plurality of points in a transmitting direction of the ultrasonic wave;
- and
- setting the transmission angle based on a tilt angle, the tilt angle indicating a tilt of the weld portion and being calculated using a gradient of the intensity for each of the plurality of points.
A weld inspection device,
- the weld inspection device being configured to perform
- causing a probe to transmit an ultrasonic wave toward a weld portion at a transmission angle and to detect an intensity of a reflected wave from the weld portion at a plurality of points in a transmitting direction of the ultrasonic wave,
- setting the transmission angle based on a tilt angle, the tilt angle indicating a tilt of the weld portion and being calculated using a gradient of the intensity for each of the plurality of points.
A non-transitory computer-readable storage medium storing a program, the program:
- causing a probe to transmit an ultrasonic wave to a weld portion at a transmission angle and detect an intensity of a reflected wave from the weld portion at a plurality of points in a transmitting direction of the ultrasonic wave;
- and
- causing a processing device to set the transmission angle based on a tilt angle, the tilt angle indicating a tilt of the weld portion and being calculated using a gradient of the intensity for each of the plurality of points.
