LABORATORY REPORT MECT 3155 Fall 2016 SECTION 1 Thursday 5:30 – 8:30 PM LAB #3 Non-Destructive Testing Student’s Name: _Johnny Martinez_____ Date Submitted: ____September 29, 2016__ Student’s ID: _____1464902___ Graded by: _______________________ Date Graded: _____________________
Objective: This lab will introduce us to various types of non-destructive testing used today. We will examine an ultrasonic test setup and application during this lab. Background: While this lab only focuses on one particular non-destructive test, there are other types as well. We will discuss three types, Ultrasonic, Radiographic, and Electromagnetic testing. The first one will discuss is Ultrasonic testing, in this test the defects in a metal are found by comparing the sonic properties of the sample with the properties of a known good sample without destroying the sample. The sound waves are introduced into the sample and the energy is reflected by discontinuities and/or the far surface of the sample. A limitation to this test is that sound energy at high frequencies do not travel well through air, so a coupling must be used. If
