Visual Inspection Analysis Methods
Visual inspection is the one NDT method used extensively to evaluate the condition or the quality of a weld or component.
It is used most effectively for the inspection of welds where quick detection and the correction of flaws or process related problems can result in significant cost savings. It is the primary evaluation method of many quality control programmes.
It requires good vision, good lighting and the knowledge of what to look for. Visual inspection can be enhanced by various methods ranging from low power magnifying glasses. These devices can also be used with television camera systems. Surface preparation can range from wiping with a cloth to blast cleaning and treating with chemicals to show the surface details.
It can identify where a failure is most likely to occur and identify when failure has commenced. Visual inspection is often enhanced by other surface methods of inspection which can identify defects that are not easily seen by the eye.
PTS also carry out Visual Inspection seminars/training to numerous companies, to maximise and enhance quality; these courses are very popular with quality managers, foreman and welders alike.
PTS have inspection teams qualified in rope access to carry out this NDT discipline without the need for scaffolding, suspension platforms and cradles. Following our inspections we produce detailed reports, including drawings and photos, and these can be supplied in whatever form is required.
