Launching in my hell hole rust repair. Need some advice on the usual welding technique for patching.
Many of the patch parts have flanges that match the factory stampings. I assume the factory spot welded these things together. Is that correct? Don't have a spot welder, and probably couldn't reach most of these locations if I did. What's the usual technique then? Drill holes in the flanges and fill with rosette welds? Or just weld the edges of the flanges? I'm replacing some sections of the main longitudinal tubes under the battery. That tube was a double walled on both the inside and outside faces. The replacement panel I have from AA has the double wall spot welded onto it. But how do I go about getting both panels weld together at the butt joint where the patch meets the original? Grind/cut the outer face back a little bit more than the inner panel, weld the inner first, and then weld up the outer? Battery tray replacement questions: - The lower support has three flanges on it. The front and side flange are easily accessible for welding, but the rear flange is turned inward. Do you weld that one too or leave it unwelded? What did the factory do there? - The easy way to attach the battery tray to the support would be to weld them together first. Is that recommended? But if you do that, then there would be no way to weld the inward turned rear flange of the support. Thanks for any and all suggestions. Andrew Blyholder |

Just to finish off this thread, thought I'd post some final beauty shots of the finished product...
Engine compartment view of new battery support and tray, fender wall behind the battery tray patched, inner face of longitudinal frame between heating duct and engine mount patched, inner trailing arm ear cracks welded. Outer view of patched longitudinal frame with new jack point gusset and new rocker jack tube. (Disclaimer: previous owners replaced the inner and outer trailing arm consoles, so all the crappy, lumpy welding around those is NOT ME. Didn't take the time to grind all that away. As bad as it looks, its seems to be holding up ok. A future project...) Before all this work, the targa top squeaked horribly. Have only been driving the car fairly short distances around town lately so that problem hadn't risen to the top of the to-do list yet. But now, those squeaks have mostly disappeared!! (IMG:style_emoticons/default/idea.gif) Hmmm...perhaps the chassis is flexing a bit less now! So glad to have this done and over with!!! Andrew |

(IMG:style_emoticons/default/av-943.gif) Seriously. You did a great job and tackled work that many won't take on! Keep an eye on it especially if you go back to AX'ing. |
