The use of laser technology for non-destructive creep crack detection.

Objectif

Many industries operate their process at high temperatures and if the operating temperature exceeds 0.4Tm (Tm= melting temperature) then creep becomes a significant problem. Welds in pipes are very susceptible to creep failure that is often sudden and catastrophic. The present method of dealing with this problem is to shut down the process to enable physical inspection. This is extremely expensive and cannot give an absolute assurance regarding fault detection. Thus, there is a demonstrable need for remotely operated, on-stream, non-destructive testing system. The development of industrial laser systerial has reached the stage at which it is possible to use the beam to excite a metallic structure, inducing a vibration. The amplitude of the vibration can then be measured by a second laser to give a good indication of component integrity. The proposed system will use only one laser, splitting the pulse to allow it to perform both the excitation and the vibration analysis.
