Why welding is more popular than riveted joints?

The welded joints provide maximum efficiency (even 100% as strong as original material) which is not possible in case of riveted joints. Alterations and additions can be easily made in the existing structures with the welding. As the welded structure is smooth in appearance, therefore it looks pleasing.

Why are rivets so strong?

Rivets fasten together two or more pieces of material of varying thickness. They won't loosen once you install them because the body of the rivet is as large or larger than the hole where it has been inserted. A rivet also won't shake out or break off, and the tight seal of the rivet helps prevent leaks and seepage.
