Even with sophisticated measuring and imaging equipment, visual inspection (or visual testing) is still a useful, relevant tool for a range of applications. Our Engaged Experts are trained to look for defects, inconsistencies, and characteristic patterns in materials, equipment and structures, helping you ensure quality and uniformity in your products and processes.

Often used in conjunction with our non-destructive testing services, a visual inspection provides you with added confidence that your products are free from defects and discontinuities. We use the industry’s most respected standards and processes to closely and carefully inspect your products, no matter how big or how large the quantity. 

How We Perform Visual Inspection (VT)

Depending on the type of material or equipment being inspected, we look for a range of different characteristics during a visual inspection. While inspection criteria are different for each project, some of the attributes we look for include:

  • Cracks
  • Corrosion
  • Surface flaws
  • Banding
  • Surface discontinuities
  • Material consistency
  • Dimensional uniformity
