FILLET WELD FRACTURE TEST

FILLET WELD FRACTURE TEST


Object:  To break the joint through the weld to permit examination of the fracture surfaces for flaws and to check root penetration and fusion.

Method: The specimen is cut to length and a saw cut, normally 2 mm deep, is made along the center of the weld face. The specimen is fractured by bending or hammer blows.

FILLET WELD FRACTURE TEST


Reporting Results:
  1. Thickness of parent material. 
  2. Throat thickness and leg length. 
  3. Location of fracture.
  4. Appearance of joint after fracture.
  5. Depth of penetration / lack of penetration or fusion.

Vickers Hardness Test

Vickers Hardness Test:- The Vickers hardness test method consists of indenting the test material with a diamond indenter, in the form of a right pyramid with a square base and an angle of 136 degrees between opposite faces subjected to a load of I to I 00 kgf. The full load is normally applied for I 0 to 15 seconds. The two diagonals of the indentation left in the surface of the material after removal of the load are measured using a microscope and their average calculated. The area of the sloping surface of the indentation is calculated. The Vickers hardness is the quotient obtained by dividing the kgf load by the square mm area of indentation. F= Load in kgf d = Arithmetic mean of the two diagonals, di and d2 in mm HV = Vickers hardness When the mean diagonal of the indentation has been determined the Vickers hardness may be calculated from the formula, but is more convenient to use conversion tables. The Vickers hardness should be reported like 800 HV/10, which means a Vickers...
