'NICK' BREAK (BEND) TEST


'NICK' BREAK (BEND) TEST

Object:  As for fillet weld fracture, used on butt welds.

Method: The specimen is cut transversely to the weld, and a saw cut is applied along the center of the weld face. The best place for the cut is at a start I stop. The specimen is fractured by bending or by hammer blows. The nick bend test will find internal defects.

Reporting Results:
  1. Thickness of material. 
  2. Width of specimen. 
  3. Location of fracture. 
  4. Appearance of joint after fracture.

CHARPY V NOTCH IMPACT TEST

CHARPY V NOTCH IMPACT TEST Object : To determine the amount of energy absorbed in fracturing a standardized test piece at a specified temperature. Method : A machined, notched specimen is broken by one blow from a pendulum. Because scatter occurs in the results, at least three specimens are used to assess the joint represented. Testing is carried out at a temperature specified in the appropriate application standard. Reporting Results: Location and orientation of the notch.  Testing temperature. Energy absorbed in joules.  Description of fracture appearance. Location of any defects. The Charpy impact test, measured in joules, is an assessment of TOUGHNESS. Transition temperature (curve) in steel.

Part - 6 Most commonly asked Mechanical Interview Questions with answer

Most commonly asked Mechanical Interview Questions  1.           Why Entropy decreases with increase in temperature? Ans.      ds=dQ/T Entropy is inversely proportional to the temperature so, as temp. Increases, entropy decreases. 2.            Why different types of sound are produced in different bikes, though they run on SI Engines? Ans.        Engine specifications are different in different manufactures like as Bore Diameter (CC), Ignition timing. Also the exhaust passage takes more responsible for sound. 3.            How much Watt means 1Hp? Ans.       746.2 Watt 4.            Explain Bicycle Rear Wheel Sprocket working? Ans.       Rear wheel sprocket works u...

Part -8 Most commonly asked Mechanical Interview Questions

Most commonly asked Mechanical Interview Questions  ·          What happens if gasoline is used in a Diesel engine?Diesel engine will work ? No, It will not work,as the Compression ratio of Petrol engine is 6 to 10 & that of Diesel engine is 15 to 22 . Thus on such high compression, gasoline gets highly compressed & it may blast. ·          Which Mechanism is used in Automobile gearing system Differential mechanism ·           Why different types of sound are produced in different bikes though they say run on SI engine Engine specifications are different in different manufactures like as Bore Diameter(CC), Ignition timing.Also the exhaust passage take more responsible for sound. ·           Why entropy decreases with the increase in temperature? ds=dQ/T Entropy is inversely proportional to the temperatu...
