Civil Engineering QUESTION #6607
Question 1
When designing a fillet weld, the effective throat thickness $t_e$ used for strength calculations of a $45^\circ$ weld with leg size $w$ is:
  • $w$
  • $0.500 w$
  • $0.707 w$✔️
  • $1.414 w$
Correct Answer Explanation
The effective throat of a fillet weld is the shortest distance from the root to the face. For a standard equal-leg fillet weld, this is $w \sin(45^\circ) \approx 0.707w$.
