subframe welds

[firebirdzig]

I just purchased a 69 Camaro subframe. It has spatter and some really thick nasty welds. I'm planning on grinding them down and possibly re welding them. Is there any advice or suggestions on how to strengthen the sub and not having to worry about it cracking later?



Thanks!

Stock sub frame or aftermarket?

Stock sub

I just did this same thing to a California rust free 69 Firebird sub frame, blasted it spotless, removed all the factory weld spatter, ground down any poor looking factory welds and tig welded up every seam, came out beautiful. It is a shame to cover up the welds with primer/paint. I have zero concerns with my welds failing in any way. Th factory welds were pretty much kept in place and I just cosmetically went over top with my welds to pretty things up.

I agree..clean it up and if possible tig weld all the factory joints. This is only because if you mig weld the joints again you will have a higher weld profile which visually you may not want.of course ask yourself if you think anyone will ever see this,chances are the answer is no

Thanks for the help!

I would recommend making sure the frame is square and measures out correct before getting to far into it. I learned this the hard way.

[firebirdzig]

Ya did that before I picked it up. The shops bought it from was pretty helpful!

I have just perched a 68’ Camaro stock front sub frame. How does one go about checking / measuring to see if you have a square and measures out frame before hand? Also is there any area on the stock sub frame to brace or make the frame stronger? I will be running ridetech strong arm coil overs level 2 system on the front end. Tks

Rewelding all the welds will likely warp the sub frame. I'd just clean the splatter and smooth off the high spots. Only welding any obvious misses.

What is a tram guage?

[raustinss]

If it's welded correctly by someone who is knowledgeable it won't warp the frame

I tram gauge is a tool which is used to help correctly measure pick up points on the car. Rather than jamming a tape measure hook into holes
