The most efficient riveted joint possible is one which would be as strong in tension, shear and bearing as the original plates to be joined. But this can never be achieved because:

Clearance is present between the plate and the rivet

Rivets cannot be made with the same material

Laser beam welding employs a vacuum chamber and thus avoids use of a shielding method
