TIG Welding Cast Iron Repair with Muggy Weld. Cast iron can be tricky to repair because it's prone to cracking. Follow along as I repair a broken cast iron skillet handle using specialty welding rods with TIG. I also show you 5 ways to determine if your part is cast iron or cast steel. This repair method uses a preheat and a cool down. For this repair I used Muggy Weld #77 welding electrodes for it's excellent crack resistance properties.
After the repair was made, I wanted to see just how strong a piece of welded cast iron really is, so I clamped the handle to the workbench and began stacking weight on the skillet until eventually the weld failed! Wait until you see the results!
This is just a demonstration. I chose to weld this skillet to eliminate any accusations that this is made from anything other than cast iron.
