Visual & Optical Testing - Level  I & II


Course Duration:     3 Days (24 Hours)                                                                                                     Course Fees:     $750


Visual & Optical Testing – Level I & II, Classroom NDT training course is developed to meet the requirements of ASNT SNT-TC-1A, CP -189 and other equivalent standards and customer specific written practice for training and certification in this method of Non-Destructive Testing personnel.
After completion of Visual & Optical Testing - Level II classroom training course you will give get in-depth knowledge of visual and optical techniques, mechanical & optical tools, interpretation, and evaluate various product discontinuities.

Training Examination & Certification Requirement:
During this Visual Testing Level II classes, you will give examination in General theory, Specification, and Practical. You are required to successfully pass these three examinations with minimum of 70% grading in each examination and average grading of all three examinations should be 80% minimum as per the requirement of ASNT SNT-TC-1A 2011.

OJT Hours: As per the requirements of ASNT SNT-TC-1A, you need to have a minimum of 210 Hours on-job training (OJT) after completion of training classes for certification in this method.

Basic Theory of Visual & Optical Testing
Visual Inspection involves using an inspector's eyes as a probing medium to detect the discontinuities in the material. The inspector may also use special tools such as magnifying glasses, mirrors, borescope, fiberscope or video scope to gain access and more closely inspect the various shape and size of parts. Visual examiners follow procedures that range from simple to very complex.
