Are you inquiring about the welds and bends?

If so, those are known as pie cuts, using straight pipe cut at angles to form a bend. Typically see a lot of this type of fabrication overseas, not so much over here.

This kind of fabrication requires many man hours complete, let alone all the TIG welding that's required.

If it was a perfect world, all metal fabrication would be joined together using TIG welds; those of you that have seen it first hand would completely agree.
