Building Construction Handbook, Eighth Edition

Structural Steelwork Connections ~ these are either workshop or
site connections according to where the fabrication takes place.
Most site connections are bolted whereas workshop connections
are very often carried out by welding. The design of structural
steelwork members and their connections is the province of the
structural engineer who selects the type and number of bolts or
the size and length of weld to be used according to the connection
strength to be achieved.
