Eddy current testing is a non-contact testing method, which mainly uses electromagnetic field and electromagnetic induction between metals to detect. Ultrasonic testing abbreviated UT, also known as ultrasonic testing, is the use of ultrasonic technology to detect work, is one of the five conventional non-destructive testing methods. An electric pulse is a pulse generated by electrons, and a pulse is a process of changing a voltage in a short time. Eddy current testing is a non-destructive testing technique in which an alternating current electromagnetic coil induces eddy currents on the surface of a metal member. Steel bar is a conventional product with high density, moderate noise. Welded pipe eddy current testing is the use of eddy current technology to test the welded pipe, this type of testing is based on the premise of lossless. The aluminum tube is a type of non-ferrous metal which may have one or more closed through holes which are thick and uniform in cross section. Tubing repair is an important measure to reduce the comprehensive cost of production in oil production plants to improve the quality of repairing tubing.
