Which of the following is a major advantage of welded connections over bolted connections?
- AHigher ductility
- BEase of removal
- CNo need for hole drillingCorrect
- DLower material cost
Solution
Concept
Advantages of welding
Step-by-step solution
1. Welded joints do not need holes, so there is no loss of net section. 2. They also need no cover plates, bolts or rivets, so the connection is compact.
Explanation
The major advantage of welding is that no holes have to be drilled, so the full cross-section of the member remains effective and the connection is simple and neat.
Shortcut
Welding → no holes, no net-area loss.
Common mistake
Choosing ease of removal, which favours bolting.
Correct answer: C) No need for hole drilling
