Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a device for grasping an electromagnetic transducer to assist non-destructive testing and a trajectory planning method thereof. Background technique [0002] Aluminum alloy plates will inevitably have defects such as cracks and corrosion during production, processing and transportation. By detecting and analyzing the waveform information obtained after the propagation of ultrasonic waves in aluminum plates, using algorithmic software to image defects in aluminum alloy plates, you can directly observe The location and size of defects in the aluminum alloy sheet can be used to reasonably select the purpose and use of the aluminum alloy sheet. [0003] Electromagnetic ultrasonic transducers have the advantages of non-contact, less affected by the environment, and mobility. Electromagnetic ultrasonic transducers are gradually replacing traditional transducers. Using ...

Problems solved by technology

By manually dividing the area and marking the position of the detection point, there will be certain errors in the use of the ruler tool, and in the process of detection, it is necessary to constantly change the position of the excitation transducer and the receiving transducer, and through the control of the oscilloscope It takes time and effort for the software to receive the data information of the transducers one by one, and at some point the position of the transducer may not be placed accurately, resulting in a certain error in the received data, and the error caused by the inaccurate position of the transducer and The accumulation of errors caused by the division of the original scale plan will have a great impact on the imaging effect
