Principle of Eddy Current Testing: Eddy current testing uses the principle of electromagnetic induction to excite the probe coil with sinusoidal current. When the probe is close to the metal surface, the alternating magnetic field around the coil generates induced current on the metal surface. For flat metal, the flow of the induced current is a concentric circle of coils, shaped like a vortex, called an eddy current. The eddy also generates a magnetic field of the same frequency, in the opposite direction of the coil's magnetic field. The loss resistance of the eddy current channel and the anti-magnetic flux generated by the eddy current are reflected back to the probe coil, changing the current magnitude and phase of the coil, that is, changing the impedance of the coil. Therefore, when the probe moves on the metal surface and encounters defects or changes in material and size, the reaction of eddy current magnetic field to the coil is different, resulting in changes in coil impedance. By measuring such changes with eddy current testing instruments, the metal surface can be identified with defects or other physical property changes. There are many factors that affect the eddy current field, such as the degree of coupling between the probe coil and the material under test, the shape and size of the material, electrical conductivity, magnetic permeability, and defects. Therefore, the problems of flaw detection, thickness measurement and sorting of metal materials can be solved by using eddy current principle


Technical parameters: flaw detection sensitivity: from the workpiece surface to the metal extending depth ≥ 0.05mm, length ≥2 mm crack, defect; When the thickness of the metal between the top edge of the crack and the surface of the workpiece is ≤ 0.2mm, the crack with a depth of ≥0.20mm and a length of ≥ 1mm can be detected.

現階段,在汽車零部件的檢測中,應用最普遍的無損檢測技術方式是渦流探傷儀超聲檢測法。在世界各國渦流探傷儀超聲探傷中應用數最多的是A型超聲波探傷儀。它選用A型超聲顯示信息,具備機器設備簡易價格低的優勢,能對缺點精準定位和定量分析,在生產制造檢測中獲得廣泛運用,可是其探傷結果存有不直觀、無紀錄、探傷難、人為失誤多等缺陷,比較嚴重危害檢驗可信性。

因為電子信息技術和電子元器件的持續發展趨勢,使超聲波金屬探傷超聲波數據信號的智能化收集和剖析變成很有可能,波型可以紀錄儲存,渦流探傷儀超聲檢測順向數據信號分析及顯像方位發展趨勢。超聲顯像技術性是一種舉世矚目的新技術應用,物件的超聲圖象可出示直觀和很多的信息內容,立即體現物件的聲學材料和結構力學特性,數字式超聲波探傷儀還能點評固態原材料的微觀機構幾有關物理性能,檢驗微觀突然宏觀經濟的不連續性。
