Evaluation of Porosity in Fusion Welded AA2014 Plates using X Ray Radiography IJTSRD
NDT has evolved as an essential demand in much modern engineering design in aircraft applications. The performance levels and reliability of the NDE is more important to the end use of the object being inspected. Failure is the primary threat to the integrity, safety and performance of aircraft structure. The aero grade material AA 2014 was taken for this project in the form of plate and welded by Tungsten Inert Gas welding TIG . The following NDT methods was done on this material Penetrant testing for to reveal surface defects, Ultrasonic testing to detect the subsurface and internal defects, X Ray Radiography for internal defects. Apart from conventional methods, remote crack inspection was carried using the Ultrasonic phased array. The results from methods were analysed. The acoustic emission test was conducted for the calibration of equipment for testing of AA 2014 material. Surface defects were detected by penetrant testing and internal defects like inclusions, blow holes, porosity and lack of penetration were detected by both Radiography testing and Ultrasonic tests. Very fine porosity was detected by ultrasonic phased array method, which could not be detected by Radiography testing and Ultrasonic testing.
