With the progress of modern science and technology, people have developed a special equipment to detect whether there is damage inside metal and non-metallic materials.Ultrasonic nondestructive testing detector is a portable industrial nondestructive testing detector, which cannot damage the detection object under the premise of the internal structure of the comprehensive detection object, but easily forms blind spots in the area of 2-3mm on the material surface and the nearby surface.Ultrasonic phased array nondestructive testing detector can compensate for this disadvantage and have high detection flexibility.This paper analyzes the advantages and disadvantages of the ultrasonic flaw detector and the ultrasonic phased array flaw detector.

This paper utilizes firstly both a scanning device and an optic fiber hydrophone to establish a measurement system, and then proposes the parameter measurement of the focused transducer based on edge detection of the visualized acoustic data and curve fitting. The measurement system consists of a water tank with wedge absorber, stepper motors driver, system controller, a focused transducer, an optic fiber hydrophone and data processing software. On the basis of the visualized processing for the original scanned data, the −3 dB beam width of the focused transducer is calculated using the edge detection of the acoustic visualized image and circle fitting method by minimizing algebraic distance. Experiments on the visualized ultrasound data are implemented to verify the feasibility of the proposed method. The data obtained from the scanning device are utilized to reconstruct acoustic fields, and it is found that the −3 dB beam width of the focused transducer can be predicted accurately.

“…Recently, the ultrasonic phased array system for nondestructive evaluation has been actively researched and developed for improving the inspection speed and signalto-noise ratio. [6][7][8][9][10][11][12][13][14] In addition, the ultrasonic sensing techniques for in-situ high-temperature monitoring have also been developed. [15][16][17][18][19][20][21][22] The conventional measurement method of the molten pool depth using a laser ultrasonic technique has been presented with a temperature distribution model.…”

The molten pool depth measurement method using an ultrasonic phased array system has been developed. The molten pool depth distribution is evaluated by comparing the times taken by the ultrasonic wave to propagate through a molten pool and a solid-phase and through only the solid-phase near the molten pool. Maximum molten pool depths on a flat type-304 stainless-steel plate, formed with a gas tungsten arc welding machine for different welding currents from 70 to 150 A, were derived within an error of ±0.5 mm.
