Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to an all-round automatic detection device for pipelines based on electromagnetic ultrasonic waves. Background Technique

[0002] Electromagnetic ultrasonic testing is an advanced non-destructive testing technology, which is widely used in the industrial field. Especially in pipeline detection, it shows unique advantages. This technology combines electromagnetic and acoustic principles, and through a non-contact method, it can efficiently and accurately detect defects such as the structural integrity, corrosion conditions, cracks, and wall thickness changes inside and outside the pipeline, providing an important guarantee for the safe operation of the pipeline. Electromagnetic ultrasonic testing technology, with its unique non-contact nature, fast detection speed, wide detection range, and strong adaptability to the detection environment, has gradually become a research hotspot and application trend in the field of pipeline detection.

[0003] In pipeline weld detection, undetected welding defects, such as cracks, pores, or lack of penetration, may cause leakage after the pipeline is put into use. For pipelines transporting toxic, harmful, or flammable substances, such leakage may lead to serious environmental pollution, fires, or explosion accidents.
