Inspection and Testing


INSPECTION AND TESTING-
In engineering activities inspection involves the measurements, tests, and gauges applied to certain characteristics in regard to an object or activity. The results are usually compared to specified requirements and standards for determining whether the item or activity is in line with these targets, often with a standard inspection procedure in place to ensure consistent checking. Inspections are usually non-destructive

 Non-Destructive Testing in great variety are in worldwide used to detect variations in structure, minute changes in surface finish, the presence of cracks or other physical discontinuities, measure the thickness of materials and coatings and to determine industrial products.

Some of the most common NDT methods are
Destructive tests on raw materials, welded joints are usually made as part of the approval OF material/ welding procedure or a welder.
Commonly used destructive tests are:
  1. HARDNESS 
  2. BEND 
  3. TENSILE 
  4. CHARPY 
  5. FRACTURE TESTS 
  6. MACRO SECTION

The Brinell Hardness Test

The Brinell Hardness Test The Brinell hardness test method consists of indenting the test material with a 10 mm diameter hardened steel or carbide ball subjected to a load of 3000 kg. For softer materials the load can be reduced to 1500 kg or 500 kg to avoid excessive indentation. The full load is normally applied for 10 to 15 seconds in the case of iron and steel and for at least 30 seconds in the case of other metals. The diameter of the indentation left in the test material is measured with a low powered microscope. The Brinell harness number is calculated by dividing the load applied by the surface area of the indentation. The diameter of the impression is the average of two readings at right angles and the use of a Brinell hardness number table can simplify the determination of the Brinell hardness. A well structured Brinell hardness number reveals the test conditions, and looks like this, "75 HB 10/500/30" which means that a Brinell Hardness of 75 was obtained us...

VISUAL INSPECTION OF WELDING

VISUAL  INSPECTION OF WELDING INTRODUCTION Inspection starts with examination of the material prior to fabrication, scabs, seams, scale or other harmful surface conditions may be detected in visual inspection. The inspector should check the following : Weld preparation, dimensions and finish.  Clearance dimensions of backing strips.  Alignment and fit up to the pieces being welded.  Verification of cleanliness.  Visual Inspection During Welding Visual inspection checks details of the work while welding is in progress. Among the details to be checked are : Welding process.  Cleaning.  Preheat and inter pass temperature.  Joint preparation.  Filler metal.  Flux or shielding gas.  Chipping, grinding, or gouging.  Post heating temperature and time.  Visual Inspection After Welding Visual inspection is useful for finished-product verification of such items as : Profile irregularities of the weldment....

HARDNESS TEST

HARDNESS TEST Hardness is the property of a material that enables it to resist plastic deformation, usually by penetration. However, the term hardness may also refer to resistance to bending, scratching, abrasion or cutting. Measurement of Hardness: Hardness is not an intrinsic material property dictated by precise definitions in terms of fundamental units of mass, length and time. A hardness property value is the result of a defined measurement procedure. Hardness of materials has probably long been assessed by resistance to scratching or cutting. An example would be material B scratches material C, but not material A. Alternatively, material A scratches material B slightly and scratches material C heavily. Relative hardness of minerals can be assessed by reference to the Mohs Scale that ranks the ability of materials to resist scratching by another material. Similar methods of relative hardness assessment are still commonly used today. An example is the file test where ...
