  • A. throats
  • B. toes
  • C. legs
  • D. roots
Correct Answer: Option C - Fillet weld–When two lapped plates are to be joined, fillet welding is used. These welds are called lap welds. • A fillet weld is approximately a triangular cross-section joining two surfaces at right angles to each other in lap joint, or tee joint. • When the cross-section of fillet weld is isosceles triangle with face at 45º, it is known as standard fillet weld. • The side containing the right angles of the fillet weld are called as legs. The size of weld is specified by the minimum leg length.
