Question

Which of the following is true about slot and plug welds?

(a) They are extensively used in steel construction

(b) They are assumed to fail in shear

(c) The inspection of these welds is easy

(d) They are normally used to connect members carrying tensile loads

The question was posed to me during an interview.

I want to ask this question from Types and Properties of Welding topic in section Welded Connections of Design of Steel Structures

Answer 1

Correct answer is (b) They are assumed to fail in shear

Explanation: Slot and plug welds are not extensively used in steel construction. They are used to fill up holes in connections. They are assumed to fail in shear. The inspection of these welds is difficult. They are useful in preventing overlapping parts from buckling.
