My brother worked for Caterpillar back in the mid 50s resurfacing tracks and boggy wheels. He was welding at 1200 amps with rods that they made at the facility. He said that they ground up the slag and used it in the mix to make new rods. Anyone ever hear of this, or has his drinking problem had an effect on his memory?
Reply:There are processes where slag is commonly recovered and recycled (submerged arc, for example). Never heard of it for manual electrodes, but it is a big wide world out there. At 1200A, I would suspect that it was SAW or a similar process where the slag/flux is supplied separately from the filler. (see: http://en.wikipedia.org/wiki/Submerged_arc_welding and http://en.wikipedia.org/wiki/Electroslag_welding )
Reply:Just guessing but I would also say it must have been sub arc.Tough as nails and damn near as smart
