You are right of course in your assertion about ease, you can quickly erect a bolted structure with a crane or a fork lift and true it all up afterwards. It doesn't matter if it rains or what the temperature is. If you set out to weld it you are at the mercy of the weather and without x-ray or other test methodology, you can't actually tell whether any joint made is actually robust or not. You also have to get it dead on first time, and hold it in place accurately whilst you weld. A nut and bolt is relatively foolproof in quality of joint terms and can be adjusted. Everyone knows what they are getting. Site welding is therefore in most cases taboo because of the cost and time considerations.
There are plenty of alternative building methods in use these days mostly involving factory prefabrication into units that can be quickly erected on site, however, history has shown that a lot of techniques that were going to revolutionise the building industry have proved to be a dangerous liability twenty or thirty years on. Thus the industry tends to stick with what it knows.
