   Forging is a manufacturing process involving the   shaping of metal  using localized   compressive forces . Forging is often classified according to the temperature:   “cold”, “warm”, or “hot” forging.   Forged parts can range in weight from less than a kilogram to 580 metric tons. Forged parts usually require further processing to achieve a finished part. Some metals may be  forged cold , but  iron and steel  are almost always  hot forged . Hot forging prevents the work hardening that would result from cold forging, which would increase the  difficulty of performing secondary machining operations on the piece.   While work hardening may be desirable in some circumstances, other methods of hardening the  piece, such as heat treating, are generally more economical and more controllable. Alloys that are amenable to precipitation hardening, such as most aluminium alloys and titanium, can be hot forged, followed by har...

 A study on the couplant effects in contact ultrasonic testing. The primary purpose of a couplant is to provide a suitable sound path between the transducer and the test surface.Ultrasonic Testing couplants usage can be seen here A couplant must effectively wet or totally contact both surfaces of the transducer and the test part. The couplant must exclude all air from between the surfaces as air is a very poor conductor of sound. The couplant fills in and smoots out irregularities on the surface of the part. The couplant aids in the movement of the transducer over the surface in contact testing. The practical couplant must be easy to apply and easy to remove. It must also be harmless to the part surfaces. How to Pick the Right Ultrasonic Couplant for Your Application? Oil or water mixed with Glycerin (2 parts water and 1 Part glycerin) are commonly used couplants. Even wallpaper paste has advantages as couplant. Heavier couplants, such as Grease or heavy Oil can be ...

  Non destructive testing for concrete Non Destructive Testing is the process of detecting the quality without destructing the material or without changing its actual properties. Rebound Hammer is also called as Schmidt hammer or Swiss Hammer or Concrete hammer test. This NDT method is used to detect the strength of Concrete Slab or rock, by identifying the hardness or elastic property. Principle of Rebound Hammer Test. Schmidt’s hammer test is based on the principle of “rebound of a spring loaded mass depends on the hardness of the concrete mass on which the mass strikes”. This rebound distance of the rebounded Plunger mass is noted down in the graduated scale as Rebound number / rebound  index. The graph in the body of hammer is used to found out the respective compressive strength. The concrete with low energy and low stiffness absorbs more energy from plunger and produces a low rebound value on the scale. Objective of Hammer rebound test...

  Welding is a process of joining metals by process of heating.  Most of the weld made are manual. It is possible that the weld may have various defect formation due to parameters of welding and poor workmanship. Why is Welding Inspection Methods  important? Therefore the weld made should be tested for defects and quality of weld metal. To ensure the joint is strong and suitable for the purpose the product is designed for. The Welding inspection methods can be broadly divided into two types Destructive Testing and Non Destructive Testing   Destructive Testing otherwise called as Mechanical Testing. It is a qualitative analysis process, which identifies the qualities like Tensile Strength, % of elongation, Hardness, Toughness, Chemical Content of metal and Micro Structure formed during welding process. But destructive testing cannot be done on all the weld joints made. Instead it is carried out on a sample per lot. Mostly the a...

  Visual Testing in NDT: Visual Inspection is method of visually inspecting the material for deciding the acceptablility of the material. Infact it is the very first inspection method in Non Destructive Testing methods. Sometimes the Visual Inspection is carried out with aid of additional Instruments and Devices such as Measurement tools & Vision aids. What are essentials for visual Inspection ? Human Eye Lighting Acceptance Criteria Measurement Devices Human Eye So in order to make sure the very essential instrument (EYE) is working properly , it is essential to investigate and make sure, it works properly. So a Visual Acuity Test is recommended Yearly, by most of the standards Visual Acuity commonly referred to as clarity of Vision. It is dependent upon optical and neural factors. i.e., (i) the sharpness of the retinal focus (ii) the health and functioning of retina (iii) the sensitivity of the interpretative faculty of the brain.
