I have been asked this question in final exam.

My question is from Design Specifications in section Welded Connections of Design of Steel Structures

Answer 1

Right option is (c) 0.7

To explain: The value of K varies with angle between fusion faces. Values of K for different angles between fusion faces are :

Angle between fusion faces

60˚-90˚

91˚-100˚

101˚-106˚

107˚-113˚

114˚-120˚

K

0.7
