Abstract

The invention discloses a phased array ultrasonic probe with an adjustable wafer array angle and an assembling and detecting method thereof. The probe comprises a probe base and a wedge block. The probe base comprises a probe shell, a locking device, a wafer array module, a connecting shaft, a coupling agent conduit and a probe cable; the probe shell is used for mounting the wafer array module; the wedge block is integrally trapezoidal, the lower part of the wedge block is processed into a curved surface, and the curvature of the wedge block is matched with that of a detected pipeline; and theprobe base is connected with the wedge block through a connecting screw. The probe is used in cooperation with a phased array ultrasonic detector, nondestructive testing can be rapidly and efficiently conducted on the internal quality of the medium and small diameter pipeline welded joint, and the probe is particularly suitable for phased array detection of the Olympic stainless steel small diameter pipeline welded joint. The ultrasonic coupling agent flow guide channel is arranged, the coupling agent can be continuously and accurately supplied to the detection surface between the workpiece and the probe when the probe moves, the use amount of the coupling agent is small and the uniformity is good.

Description

technical field [0001] The invention relates to a novel phased array ultrasonic probe and its assembly and detection method, belonging to the technical field of ultrasonic detection. Background technique [0002] The phased array ultrasonic probe uses a multi-chip integrated composite chip array for sound wave emission, reception and signal conversion, which is different from the single-chip probe used in conventional ultrasonic detection technology. The characteristics of large amount of information collection. Due to the high integration and precision components of phased array probes, it is difficult and expensive to manufacture phased array probes. At present, self-focusing phased array probes are usually used for phased array detection of welded joints of medium and small diameter pipelines. According to the specifications and materials of the pipelines to be inspected, probes with corresponding frequencies and chip array angles are selected for detection. Due to the ...
