Question: Discuss about theLaser Ultrasonic Testing for Multifarious Applications. Answer: In the field of mechanical engineering, many new technologies continue to be introduced by experts and researchers in the field, and thus increasing the possibilities of mechanical engineering and its applications to the world. One such technology is the laser ultrasonic technology used in the testing of different materials applicable in the aviation and the automotive world, as has been embraced by the innovations team at Airbus. This technology incorporates the optical capabilities of laser beams into ultrasonic investigations , so as to enable the technicians at Airbus to identify defects in different material and thus their applicability for the purpose they are used. Laser ultrasonic testing enables to non-destructive testing on the composite parts of aircrafts produced at Airbus by using high speed systems that enable the material to be examined for defects on the surface of the part(Blouin, et al., 2004). Combining the benefits of ultrasonic testing and the benefits of optical capabilities such as the laser beams, the effectiveness of the testing is increased as the testing technology is able to test defects in different materials. The technology works through the laser beam generating ultrasounds within the part being investigated during the testing process. The ultrasound is propagated through the part and out to an observation part which identifies any defects within the material or the part(Penney, 2006). The propagated ultrasound is directed to a detection laser that is sensitive to the vibration of the ultrasound as it travels within the part and these vibrations are used to identify the solid parts within the part and the hollow parts wh ich pose as defects in the part or the material. Any defects inside the part an thus be easily observed by looking at differences in the vibrations of the ultrasonic propagations, making it easy for defects within the material to also be identified without having to destroy the part (ARRTIC, 2017). This technology, being a non-destructive technology of testing, allows the materials to be tested for defects and thus their applicability for use in the field without having to cut up the part (Krautkrammer Krautkrammer, 2013). This is advantageous because regardless of the parts being made from the same material, the same material, any defects within each and every part can be tested within a matter of minutes and the applicability of the part for use be identified. Mr. Campagne in the video mentions that the laser ultrasonic tool is an easy implementation, as the laser ultrasonic testing required the beam to be propagated through the part and a diagrammatic image is portrayed for the observers who are able to tell the types of defects within the part. It also takes a short time to identify these defects and thus the technology makes investigating parts for both the aviation and the automotive industry very simple. Due to the fact that the technology utilizes optical capabilities of laser, the technology is applicable for testing parts and materials of different shapes and sizes, as the testing process only requires the laser beam to scan the surface of the part being investigated. This means that all manner of parts whether solid, hollow, or even curved can easily be scanned in a matter of minutes and this makes the industry more effective(Davies, et al., 2013). The applicability of laser allows chances of defective parts being used in the manufacture of planes at Airbus. All the materials being investigated are also safe from any impacts that they pay face during the testing process, as the technology is non-destructive. This means that the parts can also be tested from any angle and positions and without being in contact with other strong metals that may be used to hold the material in place during testing. This allows for the material to be tested for defects in the manner that the material is to be used (ARTTIC, 2017). The effect of testing parts like this is that it allows the researchers to identify specifically where the defect is and how it can affect the applicability of the material for its intended purpose. This also ensures that the inspection process takes place fast and accurately. In addition, because of the fact that the process only utilizes laser ultrasonic technology, this testing methodology can be applied to a myriad of parts of all shapes and sizes, increasing its applicability to different industries(Levesque, et al., 2012). Mr. Campagne gives examples of its applicability in in the automotive industry as well as in runways. The technology is applicable on different types of materials, ranging from metals, non-metals and even composite materials all of which continue to be widely explored in different industries in the manufacturing world today. These materials are applicable in many industries, and thus the technology can be applied for testing in all of these industries, to accomplish accuracy and flexibility in testing for defects in different industries. The technology also presents immense opportunities for the future of non-destructive testing of materials, as the Locomachs Project is looking into using the technology to test for other defects in materials, including their porosity as is explained in the video. For instance, the technology is being explored in the testing of delamination and porosity in composite materials and this presents immense opportunities in this field(Kenderian, et al., 2015). The technology of non-destructive testing by using laser ultrasonic thus presents immense opportunities to the field of mechanical engineering, which when explored can improve the quality and accuracy of material testing for their applications in the industry. Testing of materials is extremely important in industry as it helps to determine how effective the material is for its intended purpose in the field(Graham Ume, 2007). Embracing laser ultrasonic testing in industry will thus aid to make the accuracy of testing better and cheape r, as materials will not have to be altered for their mechanical defects to be identified (ARRTIC 2017). Only the defective parts can be destroyed and this ensures that the testing process becomes faster and less expensive for the different applications in industry. References ARRTIC. (2017).
