Question

As per IS 816:1969 the width of diameter of the weld should be:
1. less than three times the thickness or 25 mm, whichever is greater
2. less than five times the thickness or 35 mm, whichever is greater
3. less than ten times the thickness or 45 mm, whichever is greater
4. less than two times the thickness or 50 mm, whichever is greater
5. less than five times the thickness or 70 mm, whichever is greater

Answer 1

Correct Answer - Option 1 : less than three times the thickness or 25 mm, whichever is greater

Concept:

Where fillet welds are used in slots or holes through one or more of the parts being joined, the dimensions of the slot or hole should comply with the following limits in terms of the thickness of the part in which the slot or hole is formed:

a) The width or diameter should be not less than three times the thickness or 25 mm whichever is greater;

b) Corners at the enclosed ends or slots should be rounded with a radius not less than 1.5 times the thickness or 12 mm whichever is greater; and

c) The distance between the edge of the part and the edge of the slot or hole, or between adjacent slots or holes, should be not less than twice the thickness and not less than 25 mm for holes.
