[0002] With the continuous development of my country's economy and society, the demand for energy is growing. Thermal power plants account for a relatively large proportion of electricity supply, and it is imperative to continuously develop high-parameter and large-capacity power units. Steel structure is an important load-bearing component of thermal power units, and its manufacturing quality is crucial to thermal power units. Thermal power steel structures usually need to be welded during the manufacturing process, and after welding, the welds need to be inspected for flaws, generally using ultrasonic flaw detectors. At present, most of them are manually coated with coupling agent and then the probe is placed in the detection position. There are many detection positions, and it is necessary to manually apply coupling agent and move the probe continuously. At the same time, it is necessary to observe the data on the flaw detector, which is time-consuming and labor-intensive, and has low work efficiency.
