Mobile Welding Repair Tips When Working With Cast Iron
When it comes to welding cast iron, this is a precision job that calls for high heat and expensive equipment. You should never even attempt it on the strength of reading a brief Internet article, no matter how informative they prove to be. If you are dealing with a project that requires welding, why not call a professional mobile welding repair service like Nava's Welding? Failing that, having a better understanding of the basics could help you to prepare for a qualification course, or, to make better decisions for welding projects that you are attempting to try.
Keep your cast iron out of the range of 150 to 500 degrees Fahrenheit. As this is the danger zone for cast iron, meaning it is when cast iron is most unstable and difficult to work with.
Make sure you keep your repair patch cool enough so you can touch it safely with bare hands. Hotter patches will ruin a weld, and cold patches take too long to heat up to the right welding temperature. Consult your engineering specifications to find out what the best temperature is for your project.
Repair cracks by attaching a cast part, which will act as a patch between each of the intact parts of the cast iron. Weld patches using short welds, which are around 1 inch long, this will prevent nearby metal from overheating as you continue to work.
Use studding to reinforce any major cracks. This technique will call for you drilling some holes into the cast iron, and then screwing the patch in place. You are then free to weld the screws in place. You should expect to find small cracks in the iron once your welding is done. This is a normal, and sadly, unavoidable part of welding cast iron.
