Wanna know about cast iron welding..........

While lots of people say you can weld cast iron, you really shouldn't weld it with an arc welder......
The prefered method for repairing cast iron is to pre-heat it to about 1,000 to 1,300 degrees, and by doing so, you would braze or fuse the metal together. We use Temperature Indicating Sticks at work of varing degrees. You heat the cast iron up until the stick melts when you stroke it across the metal..............only then is the cast rady to be brazed..........



Although true you really wouldnt want to weld Cast iron because its not a strong metal to begin with it cannot support its own weight, wrought iron is a much better iron to weld its more closer to steel
