AN INVESTIGATION INTO NON DESTRUCTIVE TESTING TECHNIQUES: A SPECIFIC CASE STUDY

Abstract

This paper investigate applications of ultrasonic phased array technique over magnetic particle inspection, gamma rays radiographic and conventional ultrasonic testing applied during manufacturing of Low Pressure Heater (LPH) at a company X located in India. The existing non destructive testing techniques that are being used for detection of defects are compared with the alternative techniques. Most of the non destructive testing techniques are surely cost effective but time consuming this makes the overall stay time, production time and overall cost indulged in process high. By applying ultrasonic phased array technique the maintenance scheduling and incurred cost of maintenance and also the overall operational cost can be reduced remarkably.
