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.

全自動軸類渦流探傷機

伴隨著科技進步的發展趨勢,常見的這五大無損檢測方法自身也在不斷發展趨勢,如X射線即時顯像、全自動磁粉探傷判傷系統軟件、渦流探傷儀漏磁全自動探傷檢測系統軟件、新式滲入原材料的面世等。此外,無損檢測還增加了新的方法,如聲發射、微波加熱、紅外線、全息照相、光彈顯示信息等被稱作新五大檢驗方法。新方法也有如電子器件順核磁共振、原子平均誤差應力測試、電子衍射、無反沖力核的共震透射和消化吸收,激光器引起激波單脈沖和正電子淹沒等?,F階段,已有近50種方法被列入無損檢測的范圍。因為汽車零部件幾何圖形樣子繁雜,規定機器不銹鋼管渦流探傷設備水準高,應用原材料繁雜,規定機器設備多元化、高精度。此外,汽車零部件的生產制造是大工業化生產,有一定節奏檢測規定,且僅有減少檢測費用,才可以減少轎車產品成本,提升 在世界各國銷售市場上的市場競爭力。伴隨著社會經濟的發展趨勢,汽車產業已變成在我國的主導產業。因而。渦流探傷儀維修汽車零部件的渦流探傷儀無損檢測技術性也愈來愈遭受生產廠家和學者的關心。
