1.	Which of the following is not true regarding lap joint?(a) Connection using lap joint requires large number of erection bolts(b) It can accommodate minor errors in fabrication(c) Lap joints are well suited for shop as well as field welding(d) It introduces some eccentricity of loadsI have been asked this question by my college director while I was bunking the class.This interesting question is from Weld Defects & Types of Joints in portion Welded Connections of Design of Steel Structures
Answer» The CORRECT CHOICE is (a) CONNECTION using lap joint requires large number of erection bolts Best explanation: Lap joints offer ease of fitting and ease of jointing. It can accommodate minor errors in FABRICATION or minor ADJUSTMENT in length. They are well suited for shop as well as field welding. Connection using lap joint requires a small number of erection bolts. The main drawback of lap joint is that it introduces some eccentricity of loads, unless a double lap joint is used.
