Visual Testing(VT) Level I, II Training & Certification Courses


‘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

Visual Testing of Weld Joints

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.

Training Course on Visual Inspection VT Testing Level 2

NDT Training Courses Level 2 Certification Institute India
NDT Training Courses Level 2 Certification Institute India
Though Visual testing is simple to perform, but the skill needs are enormous. Visual Inspection technicians (as per ASNT SNT TC 1A) for weld testing needs to know about weld process, weld symbols, weld defects, study of welding metallurgy. Also he or she should have thorough understanding of welding equipment, parameters, wps and nondestructive testing means to find flaws. 
Present day ISO/ASTM and ASME standards and codes demand certification of VT technicians to at least Level1, or Level 2. Prior to certification the trainee shall have qualifications that meets ASNT SNT TC 1A. The trainee should undergo adequate class room and practical training. He or She should acquire the skills and knowledge before certification. The training course is designed to give theory and practice to test welds using Visual testing aids.
Reading of weld symbols is need of the hour for fabrication quality QA QC engineers. Unless the quality engineer understands the weld symbols he cannot perform the weld inspections. Unfortunately, our engineering curriculum does not contain reading of weld symbols as a subject. This makes our mechanical engineers not suitable for QA QC functions in weld fabrication companies.

VT Level 2 as per ASNT SNT TC 1A & ISO9712

There are two major schemes for international certification in Visual Inspection. Of them, ASNT SNT TC 1A is based on employers written practice to certify trainees on Visual testing. This scheme is of wider acceptance since 1970s. Even today, majority of the employers are using this scheme as it has capability to design and deliver training as per employers needs.
The depth of subject can cover critical aspect of visual inspection in practice on workshops. QA QC Engineers from Mumbai, Ahmedabad Gujarat, Surat, Jaipur Rajastan, and Bhubaneswar Odisha are attending the VT Level 2 courses at the center in Bangalore.
As training agent for TWI India, Chennai – we organize ISO9712 visual testing courses at Bangalore in India. Contact us now to find schedules for VT Level 2 ( welds) certification training as per ISO9712.
