2025-05-30

Flaw detection is used for offline or online inspection of surface, near-surface, inner-surface and internal defects in various metal bars, seamless pipes, welded pipes and strips (including metal materials with cross-sections such as circular, hexagonal, rectangular and square). Usually, an outer-through probe is adopted, and the tested material is linearly transported through the inner hole of the outer-through probe for detection; for online eddy current flaw detection of high-frequency welded pipes, a saddle-type magnetic saturator and saddle-type probe (usually used when the pipe diameter is relatively large) can also be used to detect the quality of welds, including defects such as incomplete penetration, inclusions, sand holes, air holes, internal burrs and internal wall welding tumors.

When the surface area of the tested material is very large, or the shape is complex (such as crankshafts, automotive parts, steam turbine blades, etc.), and the requirements are high (such as the central hole of a steam turbine shaft, metal parts, aircraft bolt holes, etc.), point probes are required, and manual or automatic scanning devices are used to achieve point-by-point scanning detection.

Different detection methods require different auxiliary equipment. Local conditions can also be taken into account, and existing equipment in the production site can be fully utilized to design special auxiliary devices for realization. For mobile sites, simple and portable auxiliary devices are usually used, and manual methods can also be adopted.
