Abstract
Aluminum alloys consist of different grade namely HE-15, 30, and 20 respectively. These alloys are selected from 6XXX series of aluminum group. All the alloys are fabricated from machining into rectangle shape in the form of 150mm in length, 120mm in width and 12mm in thickness. The main concept arises during the interpretation of alloys is defects are notified. The defects are traced out from the aluminum alloys by NDT methods, ultrasonic method and liquid penetrant method. These NDT techniques are conducted on the all aluminum alloys according to ASNT procedure to trace out defects in the materials. After, pulse-echo method of A-scans and experimented on the aluminum alloys, On the other hand water soluble dye penetrant test also performed to trace out the surface defects. Lastly, various orientations of defects are mapped out through the implementation of NDT methods and remedy behind the defects are traced out due to improper handling of welding process.
