Welding the Big Ring (1904) HD online
Welding the Big Ring
A group of men weld one area of a large ring in a fire. They lift the ring, which is hanging horizontally on chains, out of the fire. Four men hammer the hot area on the ring into shape while the remaining men hold the ring. They put the ring into the fire again, take it out, and take it over to a machine which continuously hammers down on that area of the ring. The men then take it away from the machine and hammer it themselves into shape. The ring is presumably a piece of a generator.
In the scene where four men start to weld a huge iron ring that has just come out of a furnace, one of the welders is accidentally struck on the leg by another man's welding hammer, and it is obvious that the blow has broken the man's leg. However, after he limps off screen for a few seconds, he comes back and helps finish the job.
