Like the washer idea. I always welded just a nut set on nuclear get the bolt and nut cherry red then hit it with cold water. Works good. What do you do with the washer if the bolt is broken below the surface?
You just carefully build it up and try not to use too much heat, it’s hard to get anything to stick to the cast iron unless you go crazy with the heat. Usually I can always get them out by welding, but this was an awkward position and took many attempts so it was beginning to cost too much time between attempts.
Cast iron head, iron bolts, and iron nut. You are going to weld all three items together. That trick only works with aluminum heads because the bolt and cylinder head are different metals that wont weld together unless you miss. The electron flow through the cylinder head to bolt itself will cause the two to weld together. Something my shop foreman actually taught me... I don't weld but I'm curious enough to ask why something can't be done! I am sure you learned that you made your job infinitely harder when you found out that stud welded itself to the cylinder head!
You just have to be careful and don’t go crazy with the heat. I’ve gotten many out this way…. I did show the part where more of the bolt broke off deeper in the hole and that was when I gave up because I had been getting it to move slowly each attempt, but it takes forever to clean up and let things cool down between attempts. Your first attempt is usually the defining moment and the first attempt on one side went less than ideal.
@@DadsGarageDiagnosticSpecialist Risk vs reward. Extraction set is your best bet to start. You can always attempt to weld it out after. You welded that bolt into the cylinder head... can tell because you keep breaking off parts of it deeper and deeper. We have "youtube" certified welders at our shop that weld out studs on hemi's all day long... why? Because that trick only works 100% of the time when its an aluminum head... there is quite literally 0% risk.
@verajavi12 yes one of these days I’ll get me a TIG welder. I have great success with this method… sure beats drilling a hole crooked or off center. I’ve even seen a guy drill too deep and have coolant come shooting out of the hole.
Hard work for sure and your camera work is superb !!
Thank you very much! Much appreciated.

@JrSpitty I have a lot of success doing it this way. Dunno.
I have done it this way also and it works for me too. Only difference is I carefully tig weld instead of mig to control penetration.

What kind of welder, did you use?
Miller MIG welder… not sure what model. It was having problems with the feed speed controller adjustment too. Otherwise worked fine.
Good grief! Use a tap disintegrater instead!
Used what I had.
