Was watching Modern Marvels show on welding. It had a large I beam that was cut in half because it was to heavy for the crane to lift and it took 2 guys 30 hours each to weld it together. I know it was a very large beam, but why so long???? I could think 2 guys in 8 hours could burn through a lot of boxes of rod. How many times can you go over the same weld??? Ideas???
Maybe they were doing a lot of jawing and coffee drinking... Haha
