VISUAL TESTING – VT LEVEL 2 TRAINING & CERTIFICATION COURSES
Weld Visual Inspection Courses - VT Level 2 Certification by India's Eminent NDT, Welding Experts
Visual Testing VT Level 2 Course from India’s No.1 NDT Institute
Introduction to Visual Testing
‘Visual Inspection’ VT Testing as the name indicates is quite largely used NDT Method in Industries. Especially, welding fabrication companies use Visual testing method extensively testing quality of welds. Visual testing is a versatile NDT method. That is suitable to testing of welds, castings, forgings, pipes, tubes and for even in-service inspections.
VT testing can be used for metals, non metals such as plastics, glass, ceramics and composites also. The method has wider applications in Oil Gas petroleum refineries and aerospace applications. It is well known fact that over 80% of NDT in aerospace is performed using Visual Testing alone.
Visual Testing can detect large number of surface flaws, defects including Pinholes, porosity, laps, seams, shrinkage, cracks et cetera. VT Inspection is a vital testing technique in CNC shops and automotive companies as well to weed out defective parts.
An easy and convenience testing method, visual inspection uses one’s eyes and magnfiers for direct visual examination. In indirect or remote visual examination equipment such as borescopes, fibrescope and video cameras can be of use. Direct visual inspections suits for surfaces accessible within distance of 24 inches or 2 Feet from inspectors eye. Where as Indirect and remote VT testing suits for inaccessible
Importance of Visual Inspection in Weld Fabrication
To asses the quality of weld joints, nondestructive testing method are quite useful. To detect weld defects visual testing is an economical tool. VT testing method detects flaws in weld joints such as cracks, undercuts, excess reinforcement, underfills, and slag. Also porosity, burn through, weld finish, lack of fusion, misalignment and cleanliness of weld joints.
VT inspection is a vital tool in Welding and fabrication shops to ensure quality of welds. it is crucial to identify process errors during fabrication. The Visual testing is a useful method to use atlease in three stages Viz. before welding, during welding and after welding.
Even dimensional measurements using micrometres, Vernier, profile gauges, surface finish measuring instruments are considered as visual inspection tools.
Direct & Indirect Visual Testing
Visual VT testing uses direct method or indirect inspection methods of inspection. Direct inspection method is carried out using naked eye without much usage of instruments. Ample lighting is important to perform the testing and codes standards and specification. Indirect or remote visual inspection methods uses Borescopes, Fibrescopes, Video cameras, Lenses and other visual aids.
VT testing method often used as supplement to other methods such as DPT testing or FPI testing in Aerospace, Magnetic particle MPI inspection, Ultrasonic UT inspection, Eddy current ET testing and Radiography RT testing. In addition, heat exchanger tubes inspections and weld joints testing uses Visual testing tools to check for surface blemishes and other damages before disposing the tubes in petroleum refineries.
