Ndt Ultrasonic Testing Materials,Welds
Of all the applications of industrial ultrasonic testing, flaw detection is the oldest and the most common. Since the 1940s, the laws of physics that govern the propagation of sound waves through solid materials have been used to detect hidden cracks, voids, porosity, and other internal discontinuities in metals, composites, plastics, and ceramics. High frequency sound waves reflect from flaws in predictable ways, producing distinctive echo patterns that can be displayed and recorded by portable instruments. Ultrasonic testing is completely nondestructive and safe, and it is a well established test method in many basic manufacturing, process, and service industries, especially in applications involving welds and structural metals.
Visual Inspection Welds
Visual Inspection is one of the most widely used Non-Destructive Testing methods for the detection of discontinuities before they cause major problems, e.g. poor welding, surface defects, corrosion pits, general condition, degradation, blockages and foreign materials. Visual Inspection means the inspection of equipment and structures using a combination of human senses such as vision, hearing, touch and smell. Visual Inspection is sometimes carried out in conjunction with devices such as a low power magnifying glass, boroscopes, fiberscopes, digital video borescopes, camera systems and robotic crawler systems. When attempting to determine the soundness of any part or specimen for its intended application, visual inspection is normally the first step in the examination process. Generally, almost any specimen can be visually examined to determine the accuracy of its fabrication.
Core Cutting Test For Soil Compaction,Concrete
This method covers obtaining, preparing, and testing cores drilled from concrete for length or compressive strength determinations. This test method provides standardized procedures for obtaining and testing specimens to determine the compressive strength of in-place concrete as per the standards of IS: 456. Sampling and sample preparation requirements are given to ensure that dimensional requirements are met and that the specimens are made of intact, sound concrete, and are as free of flaws as the particular structure will allow.
Liquid Ndt Dye Penetrant Testing
Dye penetration is a non-destructive method which is used to detect surface breaking discontinuities in metals, plastics and ceramics. The test is performed by cleaning the test surface thoroughly and then applying the penetrant followed by the application of developer. The developer assists to draw penetrant out from the surface breaking the discontinuities.
Rebound Hammer Testing Concrete
The rebound hammer can provide an estimate of compressive strength of the concrete according to IS:13311 (Part 2). It is a non destructive testing device, which is used on finished concrete structures, such as precast concrete septic tanks. However strict procedures must be followed if the test results are to have any validity.
