NDTTechniker

NDTTechniker, or non-destructive testing technician, is a professional who uses non-destructive methods to evaluate the integrity of materials and components without causing damage. They support quality assurance and safety across industries by identifying surface and subsurface flaws, corrosion, misalignment, or manufacturing defects in welds and structures.

Typical methods include visual inspection (VT), magnetic particle testing (MT), liquid penetrant testing (PT), radiographic testing (RT), ultrasonic testing (UT), and eddy current testing (ET). The technician selects suitable techniques, conducts inspections, interprets indications, and determines acceptability against applicable standards. They document results, prepare inspection reports, and ensure equipment calibration and traceability.

Training combines technical education with practical NDT experience. Certification standards include ISO 9712 or EN 4179 (and equivalent SNT-TC-1A in North America), with levels 1 and 2 for technicians and level 3 for experts. Certification is earned through examinations and periodic re-certification.

Industries include aerospace, automotive, energy, oil and gas, manufacturing, and construction. NDTTechniker may work on factory floors or on site, often under strict safety and radiation-protection rules, and must maintain detailed records and follow procedures.

Career paths include advancement to supervisory roles or level-3 inspector, quality assurance, or engineering support roles; some transition to research or management. The field emphasizes accuracy, reliability, and adherence to standards to ensure structural integrity and safety.
