Techniques and Tips. If you're welding cast iron to steel, the right welding method is vital. MIG welding is often the top pick, though stick welding works too. Ensure the cast iron is clean before starting. Add a preheat to control heat and avoid stress. To stop hot cracks, cool off slowly. Using peening also relaxes stress, preventing cracks.
