YASSIAN bucket teeth and bucket teeth adapter non-destructive testing (NDT)
Our excavator bucket teeth 's material is Alloy steel.The inspection of whether the bucket teeth are intact is a very important step for us.
An example of YASSIAN bucket tooth detection:
After placing the bucket teeth, evenly spray the magnetic powder liquid onto them. Then observe the fluorescence reaction to see if there are any defects on the surface.
Magnetic Particle Testing (MT)---YASSIAN EXCAVATOR BUCKET TEETH
1. Applies to: Ferromagnetic materials (e.g., steel).
Defects detected: Surface/near-surface flaws (cracks, shrinkage cavities).
Principle: Magnetize the specimen; apply iron oxide particles. Flaws disrupt magnetic flux, causing particle accumulation at defect sites.
Applications: Finished steel products, forgings, welds.
This is a picture showing a defective of bucket teeth：
2. Ultrasonic Testing (UT)
Applies to: Internal flaws in thick sections.
Defects detected: Internal cracks, voids, segregation (e.g., in boiler tubes, large forgings, castings).
Principle: High-frequency sound waves reflect off defects. Time and amplitude of echoes are analyzed.
Limitations: Less effective for coarse-grained materials (e.g., some cast irons).
3. Radiographic Testing (RT)
Applies to: Internal defects in castings/welds.
Defects detected: Porosity, inclusions, core shifts.
Principle: X-ray or gamma-ray penetration; flaws appear as density variations on film/digital detectors.
Standards: ASTM E446 for cast iron validation.
4. Liquid Penetrant Testing (PT)
Applies to: Surface-opening defects (e.g., cracks in cast steel).
Principle: Apply fluorescent/visible dye; capillary action draws it into flaws. Developer reveals indications.
Requirements: Smooth surfaces for optimal sensitivity.
Selection Criteria:
Defect Location:
Surface/Near-surface: MT or PT.
Internal: UT or RT.
Material Properties:
Ferromagnetic: MT preferred.
Non-magnetic (e.g., austenitic steel): PT or ET.
New Techniques: LC oscillator-based methods offer portability and high sensitivity for ferrous materials.
