The gold and blue coloring of shavings from work hardening is awsome.The piece the workers are forging at the end of the video will become a welding neck flange for pressure piping. It will go on to be machined and look beautiful after it is turned in a lathe and the bolt holes are drilled. I have tremendous respect for these skilled craftsman.I always love automation, but it would be useful if there was a quick caption for each thing so we know what it is.
