What does the visual method (VT) consist of?

Visual inspection (VT) is a method of assessing the condition of a component byvisual observation of the component.
Only seemingly simple, VT inspection should be applied in conjunction with other surface/volumetric methods and can provide an accurate examination about the condition of the component and any problems encountered during the performance of other inspections.
Unlike other testing methods, whose applicability depends heavily on chemical/physical or geometric characteristics of the component, visual inspection can be applied on the totality of industrial artifacts.

Where and when is visual method (VT) inspection applied?

As described by the name, visual inspection involves observing the part in order to identify precise features.
TEC Eurolab performs visual inspection according to:

  • UNI EN ISO 13018: general visual assessment of components or artifacts in order to detect anomalies (corrosion, incorrect assemblies)
  • UNI EN ISO 17637 – Direct visual examination: inspection carried out on welded joints with acceptability assessment in accordance with UNI EN ISO 5817 for the detection of defectological anomalies and shape/geometric anomalies
  • UNI EN ISO 17637 – Remote visual inspection: visual inspection performed using Videoendoscopes/Boroscopes for theinspection of welds that are not accessible by direct examination, recording the inspection and sharing the outcome to the customer with archiving of the result
  • Visual examination on castings with SCRATA surface comparators: TEC Eurolab, through the use of SCRATA comparators, determines the surface condition of castings quantitatively

ASK CONTROL VT

Visual inspection instrumentation (VT)

Although visual examination can be performed by an operator without the need for particularly complex instrumentation, the need for the fulfillment of precise regulatory requirements in terms of environmental conditions requires the use of specific instrumentation.
In particular, TEC Eurolab has:

  • Direct visual inspection kit
  • Videoendoscopes with probe diameter of 4.0 mm and cable length of 6.0 meters. Measuring and viewing heads at 0 and 90°.
  • Boroscopes
  • SCRATA panels for determining the surface condition of cast products

FAQ - Visual Method

In visual nondestructive testing, is it important to carry out thorough surface cleaning of the part?
Absolutely. Calamine, oxides, grease and dirt, in general, can mask or even cover up a discontinuity, preventing it from being detected by the inspecting operator.
All nondestructive techniques are very reliable, but each has application limitations, so the control should be designed and chosen according to the defect to be searched for.
