Using Handheld Real Time Ndt Testing

‘Jidoka’ is a system where on a production line it can automatically reject any defected part from its point of origin.

To fly was a tremendous triumph for mankind, who was previously sentenced to a life only walking the earth. Since the inception of the airplane, there has been aircraft maintenance. However, this industry has changed dramatically throughout the years and now involves highly innovative technologies and incredibly skilled technicians in order to best maintain the incredibly complex aircraft that fly in today's skies. Maintaining an aircraft is a harmonious blend between simple and intensely complicated procedures. Many procedures even still used to day are relatively simple and have existed for generations, including the basic engine work, refueling and other servicing procedures, and other after-market manufacturing that might take place on particular planes. This is now combined with impressive and innovative technologies that are highly regulated under a wide number of international agencies.

Health IT professionals may be called on to support 3D printing equipment in hospitals, research laboratories, and beyond.

Development: The Company has the new idea of a prototype. That use 3D printer to check the product that can be fit to everyone or not with safety test.

The highest of standards demanded should be set, and an additional inspection area should be added behind the most sensitive portion of the process, the Dry Film Photoresist(DFPR). This would allow items to be caught before the entire process has been completed. Additionally, upgrades in the air filtration systems of the company, and the amount of time spent cleaning the machines would likely aid in the reduction of production errors, such as the reported nicks and scratches found on reworked and returned items. Processes that run the potential of contaminating each other could also be further separated through the addition of barriers. For example, the tin striping process, which utilizes special corrosive chemicals, has the potential to contaminate the boards and should be performed in a separate room (see Exhibit XX) so that the air within that area is kept localized and filtered, and the corrosive materials in the air are removed.

Found in 1973 in Western Louisiana, Roscoe Nondestructive Testing Inc., is a company specialized in provision of testing service for large boilers of pulp and paper mills industry. Its services include monitoring corrosion of boiler walls by nondestructive testing (NDT) methods (such as ultrasonics) and provide its customers reports for the condition of boilers. With the testing information provided by Roscoe, pulp and paper mills can evaluate whether replacement or repair of their boilers is required.

Detection of corrosion damage in second layer is difficult due to a term called pillowing. This pillowing is created by aluminum oxide trihydrate which pushes the two sheets in the lap joint apart. Ultrasonic phased array NDI technique require bonding between layers for the probing energy to penetrate into the second and deeper layers, hence ultrasonic phased array accurately maps only the first layer thickness of corroded splices.

Procedure and Inspection plan with the required surface preparation for performing Inspection shall be prepared with the consultation of Material and Corrosion specialist to check weld seams and nozzles addition to visual Inspection. Using Ultrasonic shear wave testing for volumetric and crack sizing and wet fluorescent magnetic particle testing.

The depth of penetration for flaw detection or measurement is superior to other NDT methods.

Non Destructive Testing (NDT) is the testing of materials, for surface or internal flaws or metallurgical condition, without rendering it unfit for service.

The corrosion and fatigue free characteristic of composite materials has helped to reduce the amount of scheduled maintenance greatly. Aircrafts are able to have a longer interval between each scheduled maintenance by having its first visual structure check at 6 years and first heavy check at 12 years. (Boeing, n.d.) This new maintenance schedule was introduced for the Boeing 787 and the Airbus 350. Man hours for each check can also be reduced by 20%. Overall reduction of labour hours over 25 years for different checks can be seen in Figure 1. (Boeing, n.d.) The reduction of scheduled maintenance and labour hours significantly aid in the reduction of the overall maintenance cost. The longer scheduled maintenance intervals would also allow the aircrafts to sustain a longer airborne period.

The field of non-destructive testing (NDT) is a very broad, interdisciplinary field that plays a critical role in assuring that structural components and systems perform their function in a reliable and cost effective manner [4]. NDT techniques are used to locate and characterize material conditions and flaws that cause major damages to the systems and components.

This graph depicts the comparison between traditional manufacturing process and 3-D manufacturing. For a firm to test a new product in the market or for testing a new prototype they have a high cost to manufacture small units or may have a stock pile if they decide to manufacture at lower cost. 3-D printing can help reach their goal without higher cost or stock pile up.

The thesis has presented three major aspects of the EC based NDT techniques for inspection of the graphite bricks in AGR core, which are executed successfully for the duration of the PhD project. The three major areas investigated throughout this thesis are as follows:

Batches which fail are either rejected or reworked, and all material where we have identified any fault at all is returned to the supplier, and our buyers routinely threaten to place orders elsewhere. I instructed the supervisors to inspect press tooling just before the start of each production batch to ensure that there are no surface faults, so I think it is unlikely that the dents and blemishes are caused in production. I must make a point of checking that this is happening. Anyway, our final inspection sampling has been changed to give an acceptable quality level (AQL) of 2 per cent whereas until recently it was only 5 per cent. We have had to increase the number of final inspectors by four at a cost of £15 000 each per annum, but all the management team agrees that with quality products we must be confident of the final quality before packing. We trained some of our best assemblers in SPC and made them full-time inspectors; the combination of their technical and statistical skills ensures that we have the right people for this job. We could not rely on our operators to do any dimensional checks; hardly any of them know how to measure using a metric rule, let alone a micrometer or vernier gauge. It is best to keep them concentrating on achieving correct output targets. I believe that most quality problems here must be caused by occasional operator carelessness.
