cast iron block
re welding cast iron...
cast iron is a very poor medium to weld. if its a fine grain
investment casting it's ok but, an engine block is a big dirty casting. what
works best imho (btdt) is bronze brazing. i have tried oxy/acetylene, arc,
and tig. use low temp, low fuming bronze and apply a liberal coat of paste
flux (or powdered flux added to water) because you're heating a huge
heatsink be patient and heat slowly and carefully to avoid hot spots which
could burn the flux and ruin the job.
