Conventional NDT Test:
In Oil Gas Contractors and Ship repairing companies, EIWAA have its own name in non destructive testing or NDT Inspection for welding joints whether it is new or in service.All the conventional type NDT Inspection like Magnetic Particle Testing or MPI Inspection,Ultrasonic Scanning Inspection or UT Scanning,Dye Penetrant Examination or DP Test,Vacuum Box Testing,PMI-XRF Inspection,Ultrasonic thickness Gauging or UTG Examination,Leak Testing, Leakage Testing,Hardness Testing, Ferrite Testing, Holiday Detection test etc.for both welding and Painting Inspection field.Magnetic Particle testing is used to find out surface crack identification of weld joints where the welding surface is cleaned or its not in painting condition,Ultrasonic Scanning Inspection is an NDT Method used to find out the volumetric welding defects in a weld joint whether it is new weld joint or in service weld joint,Dye Penetrant Examination is used to find out the surface cracks of weld joints of non ferrous and ferrous materials,Vacuum Box Testing is an NDT Method used in storage tank and ship hull weld joints to find out the leakages by creating vacuum on the surface and by applying soap bubble solution to find out the leakages or pin holes where it is open to the atmosphere. Visual Examination is carried out by CSWIP/AWS Certified welding inspectors and NDT Test were carried out by PCN/ASNT Qualified NDT Inspector.For Holiday detection, wet sponge holiday test where the paint thickness is below 500 micron and high voltage holiday detection for the paint surfaces where the dry film thickness is more than 500 micron.Ultrasonic thickness gauging is performed by ASNT Certified NDT Inspector and by IACS Approved UT thickness instrument to verify the thickness of materials in Ship and Oil and Gas Sectors.Apart from the Basic Qualification of ASNT or PCN Certifications, all the NDT Inspector are certified by IACS Classification Approved Bodies like ABS,BV,IRS and DNV in Marine Sectors.Leak Test is a common method to determine the leak in a buried pipeline or underground pipe line where flowing pressure of more than 2 bar and the testing method is acoustic emission leak detection test.
