Yesterday I attempted to mig a casting (well the brake looked like cast) and it didn't weld at all, it was as if the gas was turned off. I have welded cast before with varying levels of success befor but nothing like this.
The "casting" was machined on all surfaces to a good surface finish and the brake was very dark grey with a very course granular structure.
Any way I ended up brazing it witch produced good results, but I am curious to what the material may have been.
