Advantages of penetration testing
a. Various materials can be detected; metal, non-metal materials; magnetic and non-magnetic materials; welding, forging, rolling and other processing methods;
b. High sensitivity (0.1μm wide defects can be found)
c. Intuitive display, easy operation and low testing cost.
Disadvantages of penetration testing
a. It can only detect defects in surface openings;
b. Not suitable for inspecting work-pieces made of porous loose materials and work-pieces with rough surfaces;
c. Penetrant testing can only detect the surface distribution of defects, it is difficult to determine the actual depth of the defect, so it is difficult to make a quantitative evaluation of the defect. The detection result is also greatly affected by the operator.
