Abstract:In recent years, with the development of air conditioning and refrigerator products and the fierce market competition,TP2 Copper Tube, as the raw material of condenser and evaporator, its performance requirements are also increasing day by day. It is an inevitable trend to use eddy current testing as the quality monitoring method in the production process of TP2 Copper tube. Combined with the application of TP2 Copper Tube eddy current testing, the basic principle and equipment composition of eddy current testing are briefly described. This paper introduces the function of testing coil and the effect of eddy current testing on TP2 Copper Tube, and analyzes the parameter setting and calibration of eddy current testing, so as to improve the yield of TP2 Copper Tube and reduce the production cost.
