NDT

INTRODUCTION TO NON-DESTRUCTIVE TESTING

What is NDT?

NDT stands for Non-Destructive Testing. In other words, it is a way of testing without destroying. This means that the component- the casting, welding or forging, can continue to be used and that the non-destructive Testing method has done no harm. The use of non-invasive techniques to determine the integrity of a material, component or Structure Or quantitatively measure some characteristic of an object. i.e. Inspect or measure without doing harm. In today’s world where new materials are being developed, older materials and bonding methods are being subjected to higher pressures and loads, NDT ensures that materials can continue to operate to their highest capacity with the assurance that they will not fail within predetermined time limits. NDT can be used to ensure the quality right from the raw material stage through fabrication and processing to pre-service and in-service inspection.

There are many NDT techniques/methods used, depending on four main criteria:
• Material Type
• Defect Type
• Defect Size
• Defect Location
Some Uses of NDE Methods?
• Flaw Detection and Evaluation
• Leak Detection
• Location Determination
• Dimensional Measurements
• Structure and Microstructure Characterization
• Estimation of Mechanical and Physical Properties

NDT Applications in different areas are:
• Service Inspection Companies
• Foundries
• Rolling & Forging Mills
• Petro Chemical & Refineries
• Mining & Mineral Processing
• Aircraft Maintenance & Manufacturing
• Vehicle Maintenance & Manufacturing
• Engineering Firms
• Research & Development Facilities
• Education & Training
• Equipment Manufacture

Who can do NDT?

Mechanical engineers
Diploma in mechanical engineering
B.A, B Com, Bsc or intermediate students
