I Want to see the correct way to see a spot weld removed? does anyone have before and after pictures thanks

 

Drill?

 

ok, well this is what im confused on do u drill completey through both pieces of metal or do u just tryin drill through the top layer only? also is their special drill bits u have to use? sorry to sound like a new b

 

there's a special bit that has a retractable point on it. you just make a dent in the middle of the spot weld, put that point in there, the drill away. Depending on what you want to take off, it could just be the top section or you might have to drill through everything.

 

well say ur removing radiator supports or firewalls or something would u just drill all the way through the spot weld?

 

you should drill all the way through the weld. if you didnt have to, how do you think that weld is supposed to hold up if it didnt penetrate through all they way? you can always spotweld it back up to fill up the whole you drilled out. thats how i was always taught anyway. either that or you got to be very carefull with a really wide flat drill bit, like a milling bit, and mill out the portion you want off. and make sure its larger than the complete weld or it will still stick. or just grind it off around the top weld with a grinder. worked well when all my bits were jacked up to redo my radiator tabs on my support.

 

The picture speaks for itself.

That is the spot weld bit I have. It works pretty good, though be careful since you will drill through both layers pretty easily. Dont ask me how I know that

not in this forum. . .

 

cool, thanks guys So I do drill through both layers right for radiator support removal

 

No you only need to drill through the first layer of metal like in the pic above. Just be careful since it is hard to tell where the first layer stops and the second one begins. I drilled through on a few holes by accident. I found that if I seperated the metal a bit on the side with my air hammer so it was under tension when I drilled the spot weld the front layer would pop off while I was drilling. That kept me from going all the way through which is real easy to do by mistake.

The tool I used to remove spot welds has a spring loaded tip. I make a spot in the center of the spot weld for that tip to follow then the toold just cuts arround the spot weld. It sorta looks like a small hole saw. For some reason my ImageStation pictures aren't working or I would post a picture of it.

I like the one you posted better because there is very minimal, if any, material left to grind down. The tool I use I need to grind down the rest of the spot weld but it does work good. Plus I got it for free from my moms boyfriend.

 

real men arc air spot welds out.

 

sure... if you have access to that sort of tools.

 

I used a broad point drill bit with a drill stop on it.

But it's always easier/better when you have tools ment for the job.

 

I have allways used a Rota Broach

The tool I use looks like that except the one I use is only one sided and has a spring loaded center point instead of a 1/8" drill bit.

 

Nice man

 

Have you ever heard of a Blair brand spot weld drill bit. Extremely fast easy, a great tool. You should be able to pick one up at Wesco.

 

when i replaced my core support, i used a combo of carbide tip drill bit, and a chissel

 

also, i drilled all the way through on most, all i did was re-weld the new core support from both sides. worked fine for me.
