CUTTING THROUGH GEAR'S TEETH FOR TENSILE TESTING AFTER CASTING AND MACHININING

Mechanical testing or engineering tests are performed to determine various mechanical properties of materials such as strength, hardness, ductility, toughness, brittleness, etc. The precision results of these tests is utilised to determine suitability of materials for the field application. ...
charpy or impact testing is widely used to measure the toughness and ductility of the weld metal, base metal. Tensile testing of welds in place, with weld metal, HAZ, and base metal, allows an overall strength to be determined but usually cannot provide the strengths of the individual parts of the weldment.
