Hey everybody....

I need input for the best way to bust a tack weld free.

When I bought my Hooker Axle-backs they had no tips. So I had some nice and unique ones welded on. Well for some odd reason the guy decided to tack weld my mufflers to my tailpipes too....which I didn't ask for.

I need to get them off without jackin' up my stuff. They are literally just a small tack to keep the muffs from moving....but now I need them to "move"....off my car...

I might sound like a hypocrite (this is assuming people read my other posts....ha ha silly me) but I found a smokin' deal on some used Corsa's, and couldn't pass them up. So after years of talking smack about $700-$800 mufflers I finally own a pair.

I don't know jack about welding so this is my first time dealing with this.

Any input would be GREATLY appreciated.

 

took some tubi exhaust off a Ferrari last month that was welded on, dremel works for that VERY well tack welds should be no trouble.

 

Thats a great idea...

I am guessing grind it a bit, hit it with a hammer to break it, and then smooth it off with the Dremel again?

 

thanks.

FYI an angle grinder works better for smoothing because they have a large flat edge but those are expensive and difficult to handle. I've seen people dismantle whole exhausts with angle grinders but this would be the pretty way of doing it.

 

I was gonna say angle grinder, but leave the guard on. If you need incentive to leave the guard on, I can dig up a photo of my teeth sticking through my bottom lip when I was 14...

 

10-4 buddy!

What sucks is my dremel tool burned up a few months back. I was grinding rust off a filing cabinet and I guess it got too hot and the motor suddenly stopped and smoke poured out of every hole and crack on the tool. I checked the brushes and they were fine...so it is in the process of being sent back to Dremel for warranty work....hope they do it.

So I do have a Hitachi angle grinder but I think its a little big for this job....

I was thinking to use my Rotary Air Tool....I might be able to fit a Dremel grinding bit on the end of it....

 

+1 with the grinding wheel. I am not a fan of those small dremels. If you have an air compressor and a 90 degree angle grinder i would use that. I just find the dremel to be slightly less powerful than kitchen appliances

 

Like others have stated... definitely a cut off wheel of some kind, will work.
Dremel is fine (just slow) or a 3M cut off wheel rigged up on a Makita or an air tool if you have access to that...

 

If its only a tack weld any cheapo grinder with a cut-off wheel will work fine! if you have access to a plasma cutter, you can even gouge out the weld as well.

 

I wish I had plasma cutter! I wish I had a lift too!

I managed to use a cutoff wheel on my craftsman pneumatic die grinder.

As of 20 minutes ago, I am enjoying the sound of the Corsas. So ferocious....seriously....yum.
