ABSTRACT: Techniques of quantitative inspection of cracks for the crack magnetic flux
leakage signal on steels based on LabVIEW is presented on this paper, quantitative testing system for crack defect on steels surface based on LabVIEW is designed, and simulation experiments are done, mathematical model is built ， the quantitative testing result to reflect on condition of crack can be acquired by quantitative analysis the signal peak-peak value, experiment results has proved the feasibility and effectiveness of the method, and relative conclusion is obtained．
