Rim is an important part of the wheels. It is often over loaded and has a complicated stress in use. Specially, at high speed circumstances, the quality of the work piece is closely connected. This paper combines the water immersion technology with the ultrasonic phased array technology to wheel detection. It introduces the basic principle, current situation at home and abroad of the water immersion ultrasonic phased array technology, and the comparison with the contacted ultrasonic phased array detection technology. According to the feature of the rim flaws, the methods to detect rim flaws with water immersion ultrasonic phased array technology are analyzed and tested. This system can finish the whole scanning in one time, improve the work efficiency and satisfy the testing requirements.

After a long run, the places of body cooperate with valve very easy to produce fatigue cracks. This cracks if not detected, extremely easy to have the accident. As the most commonly used testing equipment, ultrasonic nondestructive testing is often used to detect the engine body. However, most of the existing ultrasonic nondestructive testing equipment is used to detect whether there is a defect, there is little research the specific size of defects. According to the principle of ultrasonic emission, theoretical calculation and combined with test block, get the body phased array detection method.

Ultrasonic phased array imaging detection technology combinating the focused beam and array probe movement can get powerful test information. It has been widely used in the steel butt weld detection. For making up the limitations of 2D view, in this paper,we used one-dimensional linear array probe, got 2D slice view data obtained by phased array ultrasonic S-scan, through software programming algorithm to realize 3D reconstruction of steel butt weld typical defects. Experiment shows that it can display more intuitive performance of the defects in space. Revealing a better shape, size and orientation information. Providing a reference for the final evaluation of the defect.

Responding to non-conductive, non-magnetic material characteristics of polyethylene (PE) pipe, this paper comes up with the ground penetrating radar (GPR) detection for urban PE gas pipeline visualization research in order to solve the problems of positioning difficulty, and to avoid potential safety hazards caused by undefined positioning of PE pipeline, so that it can provide some experience to the application of position detection technology to locate buried polyethylene pipeline. Responding to the special material properties and welding form and based on the analysis of traditional ultrasonic testing for polyethylene butt-fusion joint, this paper comes up with an ultrasonic phased array dynamic focusing and S scanning imaging technology, to make a testing experiment on polyethylene butt-fusion joint. Results of the phased array ultrasonic testing of cracks in polyethylene butt-fusion joints shows that the testing method is feasible, and verifies the buried polyethylene butt-fusion joints engineering. This research would provide experience to the application of ultrasonic phased array technology in buried polyethylene pipeline inspection.

The composite insulator sheath plays an important role in protecting the core rod and insulation. The thickness of the sheath must meet the corresponding standard requirements. During the insulator manufacturing process, the core rod decentration leads to uneven thickness of the sheath, which is easy to cause the risk of composite insulators premature failure during operation. The phased array detection technology can accurately detect the thickness of the sheath, so that defects such as uneven thickness of the sheath (decentration of the core rod) can be detected, and the thickness of the sheath at the end of the composite insulator can also be effectively detected. DR detection technology can effectively identify the interface between the mandrel and the sheath, but there is a risk of the sheath thickness distortion due to inappropriate transillumination parameters.
