Welding an aluminum frame / stripped bolt?

Recommended Posts

I broke off a bolt that attaches the skid plate to the frame.

I used an EZ Out to remove the busted bolt but it wasn't a clean removal and I managed to strip and widen the hole.

I'd install a time set or heli coil for the repair but I'm wondering if I will have an alignment issue with the skid plate by doing that.

So, the question I have is whether I can use an aluminum filler rod to fill the hole and then install the time sert so I won't have worry about it being off center.

Has anyone got any advice for me on this (other than not over torquing the bolt next time I put the skid plate back on)?

If it's a mount tab and you don't get the frame rails too hot go for it, but I wouldn't weld on the rail itself if you can avoid it.  I know lots of people do, but having done an FEA on a frame before I don't advocate it.  In some places it could be very risky to anneal the material.
