Description

Technical Field

[0001] This utility model relates to the field of non-destructive testing technology for metallic materials, specifically to an ultrasonic continuous testing device for marine aluminum profiles. Background Technology

[0002] Marine aluminum alloys are widely used in shipbuilding due to their excellent corrosion resistance, weldability, and mechanical strength. However, aluminum profiles are prone to internal defects such as inclusions, porosity, and cracks during rolling, extrusion, and other processing. Traditional inspection methods mainly include ultrasonic testing, fixed ultrasonic testing, X-ray testing, and eddy current testing. Current ultrasonic testing involves a person holding an ultrasonic probe and moving it along the test area, analyzing the waveform to determine defects. However, this method suffers from low efficiency, significant subjective influence, poor result consistency, and a high rate of missed detections when inspecting long workpieces. Fixed ultrasonic testing uses a multi-probe array fixedly installed, with the workpiece passing through the test area via mechanical transmission. However, this method is only suitable for simple cross-section inspection and cannot adapt to complex structures such as T-shaped and L-shaped marine aluminum profiles. Furthermore, the inspection process is discontinuous and requires manual intervention. X-ray testing is costly and poses radiation safety risks, requiring special protection, and has a low detection rate for microcracks. Eddy current testing is only suitable for surface defects, detecting only surface and near-surface defects, lacking sensitivity to internal defects, and insensitive to internal porosity, inclusions, and other defects.

[0003] In summary, existing technologies generally suffer from low automation, poor testing consistency, insufficient equipment adaptability, and poor coupling stability, making it difficult to meet the demands of modern production lines for efficient, high-precision, and continuous testing of marine aluminum profiles. Therefore, developing an ultrasonic continuous testing device for marine aluminum profiles is of vital practical significance and application value for improving shipbuilding quality and ensuring ship operational safety.
