Re: On the other hand
Concur - I remember the building of the Sherpa at Shorts in Belfast. They didnt build parts to be as strong or stiff as physically possible - the built them to be as consistent as possible.
Thats the main reason planes mostly use rivets, (and usually many types of rivet) rather than (potentially) stronger welds. Welds (even robotic) are not as consistent - even though generally they are stronger.
