aluminum welding is called brazing


Thats not correct when you weld aluminum the best method used is Heliarc (aka TIG) you have a better finish than MIG. And then its Mig I work with guys that have 40 years plus of welding all kinds of metal and they say for Aluminum the way to go is Heliarc. Anyone can MIG weld but its takes someone who knows the art of welding to master TIG welding. Brazing This is similar to soldering in that the added material is not the same as the base material a flux is required.

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
