Q: The minimum length of intermittent fillet weld shall be:
  • A. 40 mm or four times the size of weld
  • B. 20 mm or four times the size of weld
  • C. 200 mm or 12 times the size of weld
  • D. 16 times the size of weld
Correct Answer: Option A - According to IS : 800-2007 clause 10.5.5.1 the length of intermittent fillet weld shall be 4t or 40 mm. Where, t is the thickness of thinner plate. • Maximum clear spacing between the effective length of the weld. • For the welds in compression zone = minimum of 12 × thickness of the weld or 200 mm. • For the welds in tension zone = minimum of 16 × thickness of the weld or 200 mm.
A. According to IS : 800-2007 clause 10.5.5.1 the length of intermittent fillet weld shall be 4t or 40 mm. Where, t is the thickness of thinner plate. • Maximum clear spacing between the effective length of the weld. • For the welds in compression zone = minimum of 12 × thickness of the weld or 200 mm. • For the welds in tension zone = minimum of 16 × thickness of the weld or 200 mm.
