Materials
Can you stick welding cast iron?
Quick answer
Yes — the default: nickel rods, preheat, slow cooling. Stick on cast iron: match technique to the material; filler ENiFe-CI.
The verdict and why
The default: nickel rods, preheat, slow cooling. Preheat 100–250°C, short staggered beads, peen each pass, cool slowly under a blanket — rushing it cracks the job
Watch-outs
- grind the casting skin off, drill small stopper holes at crack ends
