This paper gives the orientation and inspection of aero grade material by using Ultrasonic Phased Array over conventional methods. The dimension of material sample HE15 is 150*120*10. Two defragmented aluminum alloys are joined by welding process known as Tungsten Inert Gas Welding. Inspection of material is carried out by various Non Destructive Testing methods namely ultrasonic method, radiography method, liquid penetrant and Phased array technique. Sensitivity of material is noticed by scanning of ultrasonic phased array and pulse echo technique method alternatively defects are detected by other NDT methods namely X-ray, Ultrasonic phased array technique and LPT. Few surface flaws are noticed at a depth of 2mm by LPT method. Porosity and inclusion defects are better traceout through phased array and X-ray radiography respectively. Ultrasonic Phased Array sectorial scan technique produces immediate images, allowing straight forward visualization of the internal structure and simplifying data interpretation of weld joint. The defect is identified and located by Ultrasonic Phased array Dynamic depth focusing Technique.
