to the absence of gusset plates and other connecters, the welds are usually
process is quicker as it requires no drilling of holes.
Welding is more adaptable than other
types of connections and can even be used in circular
100% efficiency can be achieved in welding where
as the connection such as bolts can have a maximum efficiency of 70 - 80%.
produced during the welding process is relatively less.
good aesthetic appearance.
joints are air tight and water tight and can be used for water tanks and gas
joints are rigid.
of holes will never happen in welded connection.
of joints can easily be made in the case of welded connecetions.
the welded connection is having the following disadvantages.
Due to the uneven heating and cooling,
members are likely to distort in the process of welding.
of brittle fracture is more in the case of welded connections.
connections are more prone to failure due to fatigue stresses.
inspection of welded joints is difficult and expensive. It can only be done by
skilled persons are required for welding.
welding in field conditions is difficult.
joints are over rigid.
