How to Weld Cast IronTwo Methods: Temperature and Environment Welding

Welding cast iron is a precision task that requires high heat, and oftenexpensive equipment. You should not attempt it on the strength of reading abrief Internet article, no matter how informative. However, understanding thebasics can help you prepare for a qualification course, or to make betterdecisions for welding projects run by qualified personnel under yoursupervision.

Keep the cast iron out of the range of 150 to 500 degrees Fahrenheit (65 to260 Celsius). This is a danger zone for cast iron, during which it is the most

unstable and difficult to work with. This will usually mean heating or cooling the ironbefore and during the work.

Preheat the sections that require work to the 500 to 1,200 degrees Fahrenheitrange (260 to 649 Celsius).

Keep nearby iron cool, but not cold. If cold, you can sometimes run themachinery to get it up to the desired temperature.

Keep your repair patch cool enough that you can touch it safety with yourbare hand. Hotter patches can ruin the weld, and cold patches will take too long

to heat up to welding temperature. Consult your engineering specifications documentsto know the best temperature for the exact iron formula you are using in your project.

keep the nearby metal from overheating as you work.

Use studding to reinforce major cracks. This technique involves drilling holesinto the cast iron surface, then screwing the patch in place. You then weld the

screws in place as part of the repair job.

Expect to find small cracks in the iron when your welding is done. This is anormal and unavoidable part of welding cast iron. Use sealing compound for joints

and sections that must be watertight.

Always preheat or pre-cool cast iron using the same methodthroughout. Changing methods can cause stress and fractures in thecast iron. These may ruin your project, or be small enough to gounnoticed until the iron fails catastrophically during normal operation.

Cast iron is typically higher in carbon than steel. This makes the ironbrittle, and more difficult to weld than other industrial metals.
