Hi
I'm fixing an tiltrotator for my excavator where the tilt is broken of the rotor housing, the housing is made of cast steel and as I understand it's ok to weld.
I've tried welding it a little with my Mig welder but it's only 150 amp so it's not enough, so I'm using my stick welder instead.
But after trying with the mig I could see that the weld did crack so I need to figure out how to weld it without cracking.
I'm planing to preheat and let it cool down slowly, I bought some Esab OK 48.15 rods that shud be good with tension as I could reed.
Is there any other good tips for welding cast steel?
