After sand blasting (for an hout +) and parts washer I found some cracks.
2 are on the divider that seperates the waste gate gas from the turbine gas.
And one is on the torus apex (closest part that the snale thing comes to the outer most turbine blades).
Now I was going to alter this torus to flow more exhaust gas any way, it just threw me a few cracks.
I was going to heat it to 300*F + and go to work with my 135amp mig and .035'' flux core wire.
Flux core is the only way I can weld till I find out how to get a botteled gas licence over here.
What do you think is the best way to fix them?

 

The best way to weld this would be with a TIG and a nickel rod. But this would require a shielding gas (argon).

This probably did not help did it?

Cast is difficult to weld. I've only seen it done with a stick welder, and it was heated ALOT before any arc was struck. If you don't heat it it will crack again.

 

You prolly need to take it to a welding shop.

 

For repairs the local shops usaly want about $30 per repair weld.

 

Dude,30.00 dollars per weld on cast is a good deal. We charge more then that in our shop. But a GOOD nickel rod is expensive.
