Hello everyone, I am trying to set up a "nondestructive testing lab" for casting metal. Please suggest any nondestructive testing equipment. If possible, then send me the supplier address.
Thank You.
you may visit krautkramer and ge websites for the nde equipment. they are the best makers of these equipment.
TWI is one of the world’s foremost independent research and technology organizations. You can use their list....

you can use in somestimes the ultrason technique (echographie) or tomography (RX)
Some techniques are :
Liquid dye penetrant (with or without UV light), ultrasonic testing, radiography, eddy current testing, of course visual inspection, magnetic particle inspection.
YOU CAN FIND A LOT OF INFORMATION ON THE INTERNET USING e.g. the acronym
NDT (non destructive testing). There are a lot of standards and professional associations, one is given below. Good luck !

NDT methods can be roughly classified in two groups: surface techniques, which are used to identify surface and near surface defects such as cracks and surface porosity, and sub-surface techniques, that can be used to detect defects that lie under the material’s surface. In the first group, the most commonly used techniques are visual and optical testing, magnetic particle testing, liquid penetrant testing and electromagnetic testing. On the other hand, sub-surface techniques include radiography and ultrasonic testing among the most used.
Aside from the aforementioned techniques, which account for well over 90 per cent of the industrial NDT, there is a number of alternative methods each at different levels of technology readiness, such as thermography testing, process compensated resonance testing (PCRT), holography, shearography, alternating current field measurement (ACFM), and laser ultrasound.
A comprehensive description of the principles and applications of at least the classical NDT methods can be found in this reference: S. Ness, C. N. Sherlock, P. O. Moore, and P. McIntire. Nondestructive testing overview. American Society for Nondestructive Testing, 1996.
Aside from the aforementioned techniques mentioned by Prof Jose Ignacio Rojas Gregorio from Catalonia, you may use a very useful link - see bellow:

also see a very good book by Charles J. Hellier
If you want to set up a NDT lab , please visit the L&T Research and Development division for a selection of techniques and equipments. Krautkramer German equipments are well known for ultrasonic testing. Refer to standard NDT Society for testing.
Check out New England Research, Inc. in Vermont, USA. They have developed an automated table for the NDE and measurement of ultrasonic velocities (compressional and shear), (permeability) and stiffness (impulse hammer). This equipment can also be used if modified to measure the electrical properties of metals.
