The exhaust stud. I use 312 stainless electrode.
Here is one store https://store.cyberweld.com/hobart-3...80630-rdp.html I bought mine locally.
The 312 in 3/32 size burns hot enough to stick and the flux protects the metal around the bolt. I've removed a lot of broken bolts and studs that are below the surface. I weld enough to stick to the bolt adding about dime or nickle in height. I would clean and stack another bead on top, repeat until it's sticking out enough to put a nut on it, then weld it with the MIG welder or 7018 rod.
Tip: place a washer over the stud before starting. This protects the metal and forces you to be dead accurate on your welding. I used foil tape because I had it. But it protected the aluminum head from splatter.
To test the theory the flux protects the metal around the bolt. Put a nut on a bolt so its recessed, weld to the bolt and repeat so the weld is above the nut. Then put the bolt into a vise and use a wrench to take the nut off.
This also helps you get practice before the real deal. |
I've tried with and without a washer. Ran out of washers, lol and was just scrounging hardware that was laying around my garage towards the end.
I might try again before ordering that bracket. Try to stack on top of the bolt first. I might add that I'm using a cheapo harbor freight flux welder cause I don't weld enough to justify buying something nicer.
