Hello,
I need to weld a crack on a Farmall Cub engine block. If anyone is familiar, it is the casting that is typically cracked when the tractor is pulled by its front axle. Apparently, someone has attempted to repair it on the tractor in the past and this will need to be ground off to start over. It looks like they might have used a nickle rod. I am planning to remove the engine from the tractor for this repair.
Question: What is the correct procedure to do this and can I use a MIG or should I go back with a rod and if so, AC or DC-/+? What about pre-heating to prevent additional cracking? I know I need to weld it slowly and not rush the job. Can anyone recommend a good rod that I might be able to find at my LWS?
Thanks in advance.
