WELDERS NEED YOUR HELP!!!!
 

Ok, I want to mig all of my EGT senders on my stainless steel OBX >:( turbo manifold. The problem is the bungs for my my probes are brass. I have Argon gas and am using nonfluxed wire.

Will I be able to weld brass to stainless steel or will the welds burn straight through the brass?

Re:WELDERS NEED YOUR HELP!!!!
 

you can't weld two unlike metals together with a mig welder especially stainless. the only way u can weld the two together is by brazing them together. go buy yorself some brass welding rods, some flux and use a cutting torch or welding torch to heat up the base metals so they're cherry red and fill with the brass rod. its not that hard.

youu could always get some steel bungs..

Brazing wouldn't hold up to the exhaust heat would it?

Re:WELDERS NEED YOUR HELP!!!!
 

i agree with todd....i doubt brass bungs would even hold up to the exhaust heat

Re:WELDERS NEED YOUR HELP!!!!
 

Yeah, I was questionable too but no where else has anything that will match the threads of the senders. I
will just have to go with one for now in the exhaust.

Is there any other way I can mount the rest of the senders on the manifold? If I hose clamp them to the manifold, will that work?

Re:WELDERS NEED YOUR HELP!!!!
 

Yes, you can use that method. The autometer egt probe is chamfered and attached to a clamp. You just tighten it till it's sealed well enough.

It would be hard to braze them together couse brass has a lower melting piont than stainless.The brass would proabably melt away before the stainless got red.

Re:WELDERS NEED YOUR HELP!!!!
 

Yeah, one of the probes came with the hose clamp mod; but I was talking about hose claming them on the outside of the runners. I know it won't be as accurate as with gas flowing on the probes but will it still give me a decent reading?

im sure someone makes ss bungs look harder and then tig them
