Product Description

COBE carbon steel seamless pipe ET eddy current automatic testing system weld area


       Eddy current testing is based on the principle of electromagnetic induction. The excitation signal is added to the probe coil. When the probe approaches the metal surface, the alternating magnetic field around the coil generate induced current on the metal surface. For the plate metal, the flow of induction current is in the circle of concentric coils, like vortices, called eddy current. The size, phase and flow form of the eddy are influenced by the electrical conductivity of the specimen. The eddy current will also produce a magnetic field, which in turn makes the impedance of the detection coil change.
        As a result, defects or measurements appear on the surface or near the surface of a conductor. When the metal material changes, it will affect the strength and the score of the eddy current. The changes in the eddy current cause the change of the
voltage and impedance of the coil. According to this change, you can know  the defects and the change of metal materials inside a conductor indirectly.

Advantages of Eddy Current Testing:

Profiled materials and small parts
High temperature testing
No need coupling agent
Detection speed is fast and it is easy to realize automation
High sensitivity
It can detect many parameters of material, such as defect, conductivity, permeability, heat treatment, hardness, workpiece size, thickness, etc.

Application of Eddy Current Test
①Flaw detecting, can detect the flaw on the surface and sub-surface, and some flaw under the coating.
②Material sorting, can detect the conductivity on the nonmetal surface, and the related elements like chemical composition and state of tissue. Therefore, eddy current testing can be successfully used to select alloy and test material, the quality of heat treatment and mechanical properties, etc.
③Thickness measurement, eddy current can be used to test the diameter and thickness. 

GANTRY TYPE ET AND UT for large caliber oil pipe:


This off-line ultrasonic testing system can be used for big size tube testing, with high flexible, high system stability characteristics.

Step:Work piece will be neatly put onto the platform→Work pieces will be put onto the orbit by the mechanical hand→Work piece will move to the testing area, then pipe rotated, probes move right and left→when find defects, the instrument will automatic alarm, at the same time, it will display the flaw signal,record and analyse the test results, automatic sort the qualified and unqualified,and then finish the detection.
