 What are the advantages and disadvantages of welded joints?

Solution :-

Advantages of welded joints :-

1. Welded joints are more economical than riveted or bolted joints because splice plates and rivets are not required.

2. Welded joints are more rigid than riveted joints. The cover plates, connecting angles etc. in riveted joints make the joint more flexible.

3. It is because of welding that now it is very easy to joint tubular section.

4. Due to fusion of two metal pieces, the structure obtained is continuous. thus welded joints give better architectural appearance.

5. Welding process does not make large sound as compared to riveted joints and thus less noise pollution is there.

6. Because of the absence of splice plates, connecting angles etc, the drawing detailing also gets reduced thereby saving in cost and time.

7. The efficiency of welded joint is more than that of riveted joint.

Disadvantages of welded joints ;-

1. More skilled personnel are required for making welds in the metal.

2. The inspection of welded joint is difficult and expensive.

3. The heat generated during the welding process may distort the connecting members.

4. Welded joints are more prone for brittle failure as compared to other joints.
