ultrasonic testing

non-destructive testing has been around for more than forty years,this is a method of detecting internal flaws of various materials using ultrasonic waves. The use of ultrasonic oscillations to detect internal flaws has become a popular test method, giving results to small tolerances time after time. The principle of ultrasonics is based on the fact that solid materials are good at conducting sound waves, the smaller the wave length is the stronger the interaction effect on the material being tested. The ultrasonic test method is both economical and non-risk, in industries where the safety requirements are higher eg. nuclear and aerospace, radiography and ultrasonic methods would both be used.
