Mr. Mukesh Arora, Managing Director & CEO at NDTS India (P) Limited and Director at Arora Technologies (P) Limited
Mr. Mukesh Arora is a Mechanical Engineer from Mumbai University with 20 years of experience in the non-destructive testing field. He is Managing Director & CEO at NDTS India (P) Limited and Director at Arora Technologies (P) Limited, both based in Mumbai. He is currently Jt. Secretary, Mumbai Chapter and member of the National Governing Council of the Indian Society of Non-Destructive Testing (ISNT).

Non-destructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed, the part can still be used. NDTS India is the brainchild of Mr. Mukesh Arora, an NDT expert with vast experience in the field.  The company was established with a motive of building a professionally managed enterprise dedicated to the challenging field of NDT. An ISO certified company, NDTS is today engaged in sales & distribution of NDT products, On-site inspection services, Training & Certification and Level III Consulting. The company with an impressive list of customers endeavors to fulfill their inspection needs and quality assurance. “We in effect  help customers to control and ensure their product quality, “says Mr. Mukesh Arora in a one-to-one with Mr. P.K. Balasubbramaniian.  Excerpts:

Q. You claim to be a complete NDT company.  What are the products & services you offer under your umbrella?

NDTS logoAs a company, we have two major verticals: Sales & Distribution of NDT (Non-Destructive Testing) Products: Under this we represent many leading companies based in USA & Europe and look after the marketing and distribution of their products in India. Inspection Services: Under this we offer 24X7 on-site inspection services, training & certification and equipment rentals. Keeping the vision of “Make in India” our sister company, Arora Technologies (P) Limited focuses on manufacturing of NDT Accessories.

Q. What’s the significance of NDT in quality assurance? And what’s its role as an effective predictive maintenance tool?

NDT has a very significant role in QA/QC as by performing NDT you are ensuring that no bad part goes in the components.  This means minimal downtime and maximum efficiency. With continuous developments, today many techniques and tools are available for effective predictive maintenance which helps you to plan your shutdowns and enhance the life of components/plants.

Q. Which are the various methods you use for inspection?

We use most of the NDT Techniques like Ultrasonic, EMAT (Electromagnetic Acoustic Transducer), Radiography, Eddy Current, Visual Inspection, Magnetic Particle Inspection, Liquid Penetrant Inspection, Thermography, etc.

Q. What dictates the method/technique to be used for a specific job?

Essentially what you want to inspect determines the technique/equipment. If you are looking for internal cracks the choice is between Ultrasonic and Radiography; for surface cracks, you will have to choose from Eddy Current, Magnetic Particle Inspection or Liquid Penetrant Inspection.

Q. What are the various equipment you use for inspection and how often are they calibrated?

We use Ultrasonic Thickness Gauges, Flaw Detectors, TOFD & Phased Array, Multi-Channel multi frequency Eddy Current tools, Various Inspection Cameras, Wire Rope Testers, etc. As most of these equipment use the most advanced electronics, they do  not need calibration/verification like analogue based equipment,  but if you go by ISO norms it recommends yearly calibration/verification.

Q. The accuracy of test results depends not only on the equipment used but also on the professionals operating them.  Could you say some something about the cognizance and domain knowledge of your personnel carrying out inspection?

For performing NDT you have to train people and they have to be certified by various affiliations like ASNT, ISNT, ISO, etc. and depending upon their certification, they are graded as Level I (Beginners), Level II (Practitioners) & Level III (Experts).  Our team comprises ASNT Level III, and Level II Engineers & Technicians.
