Nondestructive evaluation of cylindrical parts using laser ultrasonics.
We applied the laser ultrasonic technique for detecting surface breaking slots in steel cylinders (25 mm in diameter). The observation of the detected signal over a long time (500 micros), shows that the interaction of the two contra-propagating incident Rayleigh waves reinforce the echoes coming from the defect. These echoes are slowly growing with time whereas the main signals decrease. This ...
متن کاملThe Detection of Burn-Through Weld Defects Using Noncontact Ultrasonics
Nearly all manufactured products in the metal industry involve welding. The detection and correction of defects during welding improve the product reliability and quality, and prevent unexpected failures. Nonintrusive process control is critical for avoiding these defects. This paper investigates the detection of burn-through damage using noncontact, air-coupled ultrasonics, which can be adapte...
متن کاملLaser Ultrasonics for Non-destructive Evaluation of Metal Matrix Composites
Laser ultrasonics is based on the generation of elastic waves by transient surface heating or ablation with short laser pulses. These waves are traveling through the sample, are reflected and scattered at interfaces and the backside of the sample. To realize an ultrasound measurement device we have used either an interferometer coupled to a continuous wave laser (contact-free) or the sample was...
متن کاملLaser Ultrasonics in Cylindrical Rods and Fibers
Cylindrical parts are widely used in industry at very different scales from rotating axis for engines to carbon fibres used in composite materials. Consequently, an increasing demand exists for their nondestructive evaluation. The laser ultrasonics technique providing a non-contact generation and detection process is suited for the study of acoustic waves in cylindrical structures. In previous ...
متن کاملUltrasonics: A Technique of Material Characterization
The material science and characterization is a field concerned with inventing new materials and improving previously known materials by developing a deeper understanding of properties under different physical conditions. The properties of materials depend upon their composition, structure, synthesis and processing. Many properties of materials depend strongly on the structure, even if the compo...
