NDT - Non Destructive Testing

NDT – Non Destructive Testing is noninvasive techniques to determine the integrity of a material, component or structure or quantitatively measure some characteristic of an object. In contrast to destructive testing, NDT is an assessment without doing harm, stress or destroying the test object. The destruction of the test object usually makes destructive testing more costly and it also inappropriate in many circumstances.

NDT plays a crucial role in ensuring cost effective operation, safety and reliability of plant, with resultant benefit to the community. NDT is used in a wide range of industrial areas and is used at almost any stage in the production or life cycle of many components. The mainstream applications are in aerospace, power generation, automotive, railway, petrochemical and pipeline markets. NDT of welds is one of the most used applications. Is very difficult to weld or mould a solid object that has no risk of breaking in service, so testing at manufacture and during use is often essential.

NDT is vital for constructing and maintaining all types of components and structures. To detect different discontinuities or defects such as cracking and corrosion, there are different methods of testing or inspection available. The common NDT products and methods are like Ultrasonic Testing, (UT), Radiographic Testing (RT) using X-Ray or Gamma-Ray, Magnetic Particle Inspection (MPI), Eddy Current Testing (ET), Dye Penetrant (DP), Remote Visual Inspection (RVI) etc.

Presenting The Effective Resume
Many people make one of three mistakes when writing their resume:

1.Too much information - it is not necessary to provide an over abundance of references, certifications, letters of appreciation, etc... A tastefully done resume will open opportunities to present your skills that close the deals.

2.Not enough information - You want to always give the impression that you took the time and effort to secure the job of your dreams. Give thorough descriptions of your duties under the companies you worked for. Let the prospective employer know where and when you got the experiences they may be interested in.

3.Poor formating - A plain and well written resume will usually do the trick. Most hiring managers and recruiters loathe colorful backgrounds, animated graphics and hard to read fonts. Remember... informative, direct and simple.
