It should be tightened with the help of special equipment. The failure of bolted connection can be prevented by applying high strength plate and bolt. Bolt failure How to prevention bolted connection from failure?.It is expensive for structure since welded materials can not be replaced and reused properly Failure of bolted connection It is cheaper to for structure since bolt and nuts can be replaced and reuse. The connection may loose due to the continuous vibration of the structure The welded connection remains stable for a long time even after vibration 6. It is noiseless while working which does not require special equipment for fabrication It creat noise while welding and requires special equipment for fabrication 5. It can be replaced and removed if required It can not be removed and replaced but can be repeated on the welded portion 4. i.e fire does not involve in it It is a hot process. No skilled human resource is required It requires skilled human resources 2. Difference between bolted and welded connection S.N Bolted Connection Welded connection 1. Nuts and bolt connections may loosen if there is too much vibration due to load or hammering.The bolt should be protected with pains or chemicals to prevent it from corrosion.It makes the plate weaker than the previous one. Bolt required a hole in the plate for connection, so it reduces the area of the plate where the bolt has to be connected.There may be a slip of bolt after repeatedly applying of load for a long period of time.Bolted connections in steel structures spoils the appearance of the structure.There is no chance of fire in the structure since bolt connection is the cold process of fabrication.The members connected with bolts can carry the load immediately after installation.Bolt connection can be easily replaced, retighten, and removed if there is any damage in any parts of the structure.It is not necessary to carry extra equipment to install connect bolt.Bolted connections in steel structures is simple to apply on the members ie.The connection of the bolt does not require electricity which makes it a noiseless connection.It is a faster way of installing any members on site.The shank is threaded at the end to receive the nut.Ĭommonly available nominal diameters of High strength friction grip bolt (HSFG) is 16mm, 20mm, 24mm, 30mm, and 36 mm. The size of the bolt is designed according to the diameter of the shank. ![]() A bolt is a small piece of metal equipment made up of high-strength steel.
