Are welded constructions any better than bolted?

A big communication towers form problems with transportation. For example Altruss H32 tower has base size of 4,5 by 4,5 by 6 meters. Not an easy piece to drag on a higway. Most of our constructions are hybrid  – lower sections are bolted, and upper (small ones) welded. Welded sections are quicker to install on site, and less things may go wrong with them during installation, but they are more prone to frost cracking, and welding errors. Bolted sections are little more expensive to manufacture and take more time to assembly, but transportation is cheaper and easier, plus there is nothing that may go wrong with them when assembled (bolts may become rusty after couple of years, but not much more).

As for stiffness (that is common concern) they perform the same. Bolted constructions show advantage when they are done with the job in one place (easier to disassemble and sell, or bring to another location)
