Quite impressive how this team works this very heavy hunk of steel so efficiently. Glad I wasn't born locally and recruited into this to pay for my food. Almost as bad as a Glace Bay coal mine in 1910.

wow... it's mesmerizing to watch. Obviously this team has built a bunch of these. It's remarkable the steel remained hot enough to be formed over the 13 minutes.

Did you catch the use of calipers at the very end, measuring outside diameter?

It would be interesting to compare this process to what occurs in a modern mechanized steelworks plant.

Brings back good memories for me, I was 20 when I hired on at the Southern Pacific RR. Being a Boilermaker/ Blacksmith using the Hammer was a thrill to work with, we made everything from snow plows to gears for turntables for bridges. We had to get permission from the court house in Sacramento because we shook the building downtown... good times

Forging is much stronger, yes. A casting is like styrofoam compared with a forging.

Exactly. Think of crankshafts or connecting rods in racing engines vs. your common Chevy Vega engine. All the HiPo engine parts are forged
 
From Wikipedia: Forging can produce a piece that is stronger than an equivalent cast or machined part. As the metal is shaped during the forging process, its internal grain deforms to follow the general shape of the part. As a result, the grain is continuous throughout the part, giving rise to a piece with improved strength characteristics.
 
This type of flange is used in what type of application? A Nuke Plant hopefully not.
