1. Welding takes a lot longer than bolting two profiles together.
2. TIG welding is pretty difficult, so most people would have to hire a contractor to do it, making it very expensive.
3. It's hard to make welded stuff to high accuracy. If something doesn't fit, it takes a lot of time to fix it. With bolts it is trivial to fix bad alignment.
