Key Features:
The ultrasonic probe's rotating steel pipe straight-line running method, combined with the through-type eddy current, forms an integrated flaw detection unit with the following advantages:
The ultrasonic and eddy current techniques are combined into one, merging the two flaw detection methods with complementary performance characteristics. This allows for a more effective enhancement in detecting natural defects.
2. Merging the two machines into one reduces the footprint, as well as the number of operators, auxiliary personnel, and transportation steps, significantly enhancing operational efficiency.
3. A sub-machine was reduced in the equipment set, enhancing the equipment's usage efficiency and detection quality, offering a higher cost-performance ratio.
