Why NDT as a career option


Non-destructive Testing as a career option is one of the lucrative opportunities for engineering (Mechanical, Metallurgy, Aeronautical, Petroleum branches ) and diploma holders in many manufacturing industries in India.  
With a couple of years of experience, the doors will be opened in many International manufacturing hubs like Germany, Singapore, USA, Dubai and the middle east

Sectors which have NDT jobs

  • Automobile
  • Defence (DRDO, DRDL, DMRL, etc)
  • Aerospace (HAL, TATA Aerospace, etc)

Trainer Success Stories


Rambabu Musini
 Quality Engineer

 "I am lucky to say that I got trained by one of the finest teaching faculty versatile by his knowledge and teaching style where a student understands the concepts very well. His concept-oriented teaching methods make students feel confident and can apply practically by his teaching methods. Here I am not exaggerating by saying so but as an average student, I am saying this by my heart. I have got to learn both certifications i.e., ASNT LEVEL II & NAS 410 from Srinivas Sir." 

Vinod Kumar
Managing Director

 "The methodology used by Srinivas was laced with ample examples related to the real job application which was simple, yet effective in enhancing ghte knowledge of our team."

Frequently Asked Questions (FAQ)


Course completion certificate will be given by NDT PLUS on successful completion of course.

Industrial accepted (NDT LEVEL-1 OR 2 Certification will be issued by NDT level-3 (given by Certification governing bodies like American Society for Nondestructive Testing (ASNT) upon the meeting of norms of SNT- TC- TC- 1A (Education, Experience, Training and Certification)

YES, For entry-level positions, companies will look for candidates who have the understanding of the methods and how to conduct them rather than recruiting candidates with ZERO knowledge in NDT and getting them trained to meet the industrial need. In this regard, Certificate issued by NDT PLUS is suitable so that you can start delivering your job.

Regarding authenticity to certify the quality of a product, NDT LEVEL -2 certificate issued by ABOVE CERTIFICATION BODY is required for which the candidate should meet the above-mentioned norm
