Q: Which one of the following is the mode of failure in a fillet weld material?
  • A. Tension
  • B. Shear
  • C. Bearing
  • D. Crushing
Correct Answer: Option B - Fillet weld– Fillet welds are commonly used to join two material pieces at right angles. • The shear strength of the weld material depends on several factors, including the type of welding process, the welding parameter, and the properties of the base metal. • Shear failure occurs when the applied shear stress exceeds the shear strength of the weld material. • In fillet welds, the shear stress is highest at the throat of the weld.
