So after some thought and discussion about modifying the torsion bars, I think I need some advanced knowledge about metallurgy. I have been a welder for over 20 years working mostly in aerospace and medical equipment and have a lot of geeky knowledge but i don't know everything.
My existing dogbones are the round bar style and were cut in half, and spliced with a longer middle piece of pipe. I want to do similar the I-Beam style I have.
Anyhow, The I-beam style dogbones seem to be a type of cast iron.
I know when welding most cast iron a minimum of pre-heat and post heat is required. It also needs to be welded with Ni-Rod (welding rod high in Nickel). The slower the cooling process helps prevent thermal shock and crystallization of the metal causing cracks and brittleness. Usually when i weld cast iron I place the part in a bucket of sand and cover it with sand.![Whistling :whistle: :whistle:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
can anyone provide any more information about this?
