This is a method I use fairly often for cast iron repairs, using a TIG welder and silicon bronze filler rod. Broken part is sand blasted, with most attention on fracture area.
Set up parts so fracture is aligned just "sitting there", a clamp and shims can help.
Grind away material to gain surface area for the silicon bronze to adhere to but leave enough for the parts to be perfectly aligned at the cleave.
Tac either end, top and bottom, make a root pass and come back with a few more to fully fill the joint.
Sand it, if you want it to look pretty.
