Non-Destructive Testing
Nondestructive testing (NDT), also referred to as nondestructive examination (NDE) and nondestructive inspection (NDI), refers to any testing systems that do not permanently alter the workpiece or object being tested. NDT is useful in a multitude of fields, and can be performed on a wide variety of substances, including metals, food products, historical objects, and medical equipment. In manufacturing, NDT is a useful process for verifying a weld. NDT is capable of discovering cracks or porosity inside a weld, along with variations in density, that could result in a break or rupture. Common NDTs include visual inspection, ultrasonic, radiographic, liquid penetrant, magnetic-particle, and eddy-currant testing.

Laser weld inspection systems using 3D imaging can improve productivity and quality control of ERW and HFI tube welding by working in conjunction with other NDT testing.
Quality and characteristics of the product material, fitting tolerances, and overall cleanliness of a surface or particle load all contribute to the measurable technical cleanliness of automotive components, an integral factor in upholding rigorous requirements on emission reduction, fuel efficiency, long-term durability and regulatory standards.
This review of some new products shows how advanced technologies are bringing flexibility and a wider range of applications to NDT inspection booths, pre-inspections and screening applications used in shops.
