Some advantages of welded joints over threaded fasteners are that
1. They are inexpensive and there is no danger of joint loosening. The
welding allows the arrangement of the structure components, in such a
way, the joint provides maximum efficiency, but it is possible in case of
bolted joints.
2. Additions and alterations can be easily made in the existing structures.
3. In welded connections, the tension members are not weakened as in
the case of bolted joint. A welded joint has a great strength.
4. Sometimes, the members are of such a shape that they afford difficulty
for riveting. But they can easily weld. The welding provides very rigid
joints. It is possible to weld any part of structure at any point. But bolting
requires enough clearance.
5. The process of welding takes less time than the bolting. No need to
drilling and measuring.
