This is an international forum, where on the planet are you?

The industry has many different aspects and routes of entry, if you already are trade based you can take a weekly course at a local college and get into the labour end of X-Ray assistant or Ultrasonic thickness surveys, ground penetrating radar operator, drone operator etc.

If you have the time there are 1 year NDT foundations courses at various colleges in Canada, USA I can point you to, programs in Canada are about 12,000 CAD for the full year. Other 2 year technology programs such as Welding Engineering Tech, Materials Tech etc get you well on your way for the higher end of the market sector.
