Visual Testing (VT)

Visual Testing is one of the most widely used Nondestructive testing method and is used in almost all industries to identify defects and discontinuities in part. For visual testing good eye sight is required either natural or corrected. Defects or discontinuities are enhanced by mirrors, magnifiers, Borescope and other various visual aids.

Visual examination is performed usually at a distance of approximately 10” to 24”. Light requirement for Visual testing Inspection is minimum 150 Lux and it increases as seriousness of discontinuities increases. In general residential light requirement is of 200-250 lux for normal vision and minimum contrast of 3:1 for lighter objects and dark background.

Advantages of Visual Testing

1. Visual Testing is less expensive method as compared to any other NDT method.

  • It is very convenient to perform visual inspection at different place, hence it is very portable method.
  • After inspection results of inspection is immediate and this makes visual inspection as one of the fastest NDT inspection method.
  • Moderate skill is required for visual inspection.
  • Work piece or specimen can be inspected with less part preparation also.

Disadvantages of Visual Testing

  • Only surface defects can be viewed by visual inspection.
  • Micro or small defects are not visible to unaided eyes.
  • Confusion occurs between relevant indication and non-relevant indications.

Eligibility For Visual Testing NDT Training Level I, II Certification Courses

Eligibility, qualification and experience requirements as per written recommended practice of SNT-TC-1A, 2016 Edition are given below.

Non-destructive testing courses are considered as the most valuable professional courses to improve individuals’ skill sets and ladder for the steep career growth in quality control QA/QC functions in manufacturing and processing industries. These courses are especially considered as short term professional courses for any Mechanical, Metallurgical, Civil, Electrical and other engineering professionals. Based on proficiency requirements, certification is offered for NDT level I, level II and NDT level III. In order to be eligible for each NDT level, the individual should meet the required eligible criteria.

Candidates interested in certification of non-destructive testing should have sufficient education, training and experience to ensure eligibility in required NDT methods in which they are being considered. Candidates with diploma in Engineering or bachelor’s degree in Engineering (Mechanical engineering, Metallurgy, Civil or any engineering) or bachelor’s degree in math, science or plus 2 / intermediate with math, science are eligible for the courses. Depending on NDT level chosen, method selected, candidates with other educational qualifications also are eligible provided if they can meet the following recommended criteria.

In addition, the candidate must meet the following other eligibility as per the written practice.
