Abstract
Automated ultrasonic testing method will be used in the many industries to locate discontinuities and to detect internal defects under test inside the workpiece material. The lowest defect size in weld material may start from 0.5 mm onwards. Ultrasonic testing is a fast and automated method, because the signals are available in electronic form to be tested in plates and pipes. This is mainly used for whether the material will be accepted or rejected easily based on internal cracks. “Modsonic Einstein II TFT (MODSONIC)” software package has been extensively using in many industries to find flaws and cracks. The objective of the work is to find the flaws in various materials like mild steel (M.S) plate clad with mild steel (M.S) electrode, mild steel plate clad with brass electrode, mild steel plate clad with stainless steel electrode, mild steel pipe clad with mild steel electrode. To detect the flaws at various angles, the probes are placed at 45°, 60° and 70°. When the size of the weld plate is less than 25 mm, then it will be preferable to use and find flaws in materials with 70° probe angle. With MODSONIC software package, it is found that mild steel pipe welded with mild steel electrode highlighted more internal flaws at 70° probe angle from experimental analysis.
