Quenching the area with water (spraying it), to my understanding, causes the bracket to shrink, causing it to grab harder. Correct me if i am wrong, but leaving it might have worked better. This is what I have learned from doing this a few times.
Yes, but heat cycling is what helps break the corrosion. My dad's rule of thumb was always to heat it like hell and then cool it quickly with cold water three times. The expanding and contracting will break the corrosion, and then it will come out much easier. Often just heating can work, but not always.
Spraying the item you want to remove causes it to rapidly shirnk and release the threads, Old mechanic taught me this when I were a young mechanic and I use this everyday for brake bleeders, you can use plusgas or WD40 also but bare in mind the fumes.
Well done - next time if you press a regular wax candle into the back side of the hot fastener it will wick up the threads and makes removal a lot easier. Penetrating oils just burn off.
Never cool down a welded on nut with water that will make the metal brittle so it will crack again when put force on it. just take a few minutes to let it cool slowly.
I've got to try this with my everlast welder the next time it happens. I've found that impact will sometimes loosen the bolt but that is often not feasible because of the part or the location.
If you use a petroleum based penetrate, wouldn't draw the oil into the weld and make it fail? You would have to get it hot enough to get the oil out before the weld would hold.
would have worked the first time if you had let the weld cool down before you tried to turn it .when you welded the bolt it expanded inside the hole making it tighter . if you had let the bolt cool down it would have came out first try .
good to see real life efforts as a lot of videos show this is easy, when clearly its not.. cheers
Your persistence is inspiring!
I bet the heat from welding also helped break the bolt loose.
How come I did not come here early?...I got exactly the same situation. Will try it tomorrow! Thanks for the tips.

I really am not sure to be honest, but I believe you may be correct.
YOU ARE RIGHT .. THE HOTER THE BETTER , IT WILL COME OUT

only problem after bit the metal gos weak

That was a good idea drilling to get a better weld.Must have been a good drill bit.

what if its in the chassy like mine i have only the threds from the nut
May have to drill it out if you have room
THANK STEVE NICE ONE

First couple try u turned the snapped bolt wrong way around but last try u got it right well done
Great idea drilling the hole
Nice method at the end good job way to stick with it!

We’re you using gas with your welder (Mig)? Or no-gas fluxcore? If flux, what size wire? I’m having a bear of a time getting one out. Thanks. 🇨🇦👍🏼
can you use this method on aluminum head ? I have a broken exhaust manifold stud on my honda accord.
No need to spray after welding. Moving it while its red hot will help to loose the stud
Awesome video thank you for sharing.

Is retapping not as strong as original threads? If not, is it way less strong or similar?
This man needs some candle wax
Nice work
you after put heat on that manifold ear with oxey acclene also
Good job
Hope you used some anti seize to put it back in
would have worked the first time if you had let the weld cool down before you tried to turn it .when you welded the bolt it expanded inside the hole making it tighter . if you had let the bolt cool down it would have came out first try .
You should never turn it clockwise cause it just put more stress on the welded part. Trust me I have done this numerous times.
My welds Keep breaking while trying to do this 5 hours spent so fsr
been a welder for 40 years and av never put water on a weld that was one of your problems
👍👍👍👍👍👍👍👍👌👍👍👍👍👍👍👍
heat it up man
