Description

Technical Field

[0001] The utility model relates to the technical field of weld detection, in particular to a phased array ultrasonic detection device for bidirectional stainless steel. Background Art

[0002] Duplex stainless steel is made up of approximately 50% ferrite and 50% austenite, with the minor phase typically requiring at least 30% of the material. Phased array ultrasonic testing devices use an electronic system to control the excitation time and phase of the ultrasonic probe elements, thereby focusing, deflecting, and scanning the sound beam. This enables multi-angle and multi-depth inspection of the object being tested, yielding more comprehensive and accurate results. This technology is widely used in a wide range of industries, including aerospace, petrochemicals, electric power, rail transportation, and shipbuilding.

[0003] Existing technologies include the utility model with publication number CN217385337U. This utility model relates to the technical field of weld detection and discloses a phased array ultrasonic detection device for steel pipe welds. This utility model includes two right-angle frames and two hand-tightened bolts. The right-angle frames are inserted into each other to form a rectangle. The right-angle frames include a straight rod, a flat fork section, and a push rod. One end of the push rod is fixedly connected to one end of the straight rod. The push rod and the straight rod are perpendicular to each other. The flat fork section is fixed to the end of the straight rod away from the push rod. A slot is provided in the middle of the flat fork section, and a positioning slot is provided on the flat fork section. The push rod is inserted into the slot. Positioning threaded holes are provided at intervals on the push rod. The hand-tightened bolts pass through the positioning slot and are connected to the positioning threaded holes. A phased array ultrasonic probe unit is mounted on one of the straight rods. By pressing the two right-angle frames toward the steel pipe to be inspected and pressing the rubber wheels against the surface of the steel pipe, and then tightening the hand bolts to lock the positions of the two right-angle frames, this design is ingenious and can adapt to pipes of different outer diameters within the stroke range. Adjustment and installation are convenient and quick, solving the problems of complex structural design of existing sweeping frames, cumbersome assembly, complex parts matching, and poor economic benefits in both production and use.

[0004] In daily work, it is found that when the existing phased array ultrasonic detection device is used, when it is placed on a bidirectional stainless steel pipe, it is necessary to manually adjust the device and then assemble it with the steel pipe. Subsequently, the device needs to be manually controlled to perform rotation measurement at the weld. This tedious operation requires a lot of physical strength and energy. Long-term manual rotation and clamping can easily cause operator fatigue, which may affect the accuracy and stability of the detection, thereby causing the existing phased array ultrasonic detection device to be inconvenient to use.
