When a component can be seen, visual testing is the first method used in an NDT examination. This is the most common, easiest to perform and low cost NDT method.
Visual inspectors are trained and certified to detect surface discontinuities Part of that certification includes the ability to recognize Level 2,W59-18 weld acceptance criteria. Focus NDT can provide visual testing technician training for level I and level II certification.
These are foundational certifications and becoming qualified in visual testing is a great career starting point for NDT technicians.
