10.1 Introduction

Nowadays most of the connections in steel structures are carried out using welding since it is efficient and economical. It does not require holes to be made in the members to be connected and can be done without extra material such as plates and angles. Both butt welds and fillet welds may be used for connections. Butt welds are most economical since connecting parts are welded directly without any plates or angles. However, it is not possible to do all the connections in a steel structure using butt welds due to misalignment and misfit during erection. For example, to use a butt weld, in the case of a beam to column connection, the tolerance on the gap between the column and the beam is very stringent. ...
