    BEND TESTS

    BEND TESTS Object:   To determine the soundness of weld metal, heat affected zone and weld zone.These tests may also be used to give some measure of the ductility of the weld zone. It is not usual to use transverse and longitudinal bend tests for the same application. Method:   All specimens to be removed and prepared without causing significant distortion or heating. The cap and root are ground flush. The specimen is bent by the movement of a former of prescribed diameter, the relevant side of the specimen to be placed in tension. Angle of bend and diameter of former should be as specified in the appropriate standard. Reporting Results: Thickness of specimen Direction of bend (root or face) Angle of bend Diameter of former Appearance of joint after bending e.g. type and location of flaws

    Part -3 Most commonly asked Mechanical Interview Questions

    Most commonly asked Mechanical Interview Questions with answer 1. What is the difference between Technology and Engineering? Ans. Engineering is application of science. Technology shows various methods of Engineering. A bridge can be made by using beams to bear the load,by an arc or by hanging in a cable; all shows different technology but comes under civil engineering and science applied is laws of force/load distribution. 2. How to Measure Temperature in Wet Bulb Thermometer? Ans. Wet bulb temperature is measured in a wet bulb thermometer by covering the bulb with a wick and wetting it with water. It corresponds to the dew point temperature and relative humidity. 3. What are the Advantages and Disadvantages of using LPG in Car? Ans. Advantages 1. Complete combustion 2. Fuel saving 3. Homogenous combustion Disadvantages 1. As complete combustion is occurring ,more heat liberated,not advised for long journey, engine will be over heated 2. In...

    DESTRUCTIVE TESTING

    DESTRUCTIVE TESTING 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: Hardness  Bend  Tensile Charpy Fracture tests Macro section TYPES OF TEST Quantitative (For measuring a 'quantity')  Tensile Charpy Hardness C.T.O.T. (crack tip opening test) Qualitative (For assessing joint 'quality') Bend test Nick break  Macro Fillet fracture The test pieces are cut from the test weld and their location is often specified in the standard. The areas for test are shown below.
