Ultrasonic Testing:A State-of-The-Art

This paper attempts to present the basics of the ultrasonic testing of materials and the general way in which the testing equipment operates. In structural fabrication or in the manufacturing of machineries raw materials play a very important role. Internal defects in raw materials have considerable influence on the strength of the product.

A good product means free from harmful flaw and possessing the requisite strength to achieve desired performance.

Destructive tests give the properties of raw materials used which are mainly made on the samples prepared form the similar material as the same cannot be made on the main products which are to be delivered to a customer. For this reason use is often made of certain forms of Non-destructive testing, of which ultrasonic testing is one the important methods, which the author has tried to explain in his paper
