Porsche 914 Inner Wheel House Repair continued...

Now the rusty metal and crappy repair job done by a previous owner have been cut out - and the replacement panel has been cut to fit the hole, it's time to weld it in. The fit is pretty good.

I used conventional welders clamps together with Integrips to hold the panel in place.. here are pics from the outside and inside before welding.

And here it is tack welded into place.. You've got to be pretty strategic as to which points you tack weld as you move around the panel, so that it doesn't shift or stretch due to the heat of the welds. 

From the inside, you can see the plug welds I made to attach the panel to the inner structure of the Sail Panel.

It's also important that when you weld such thin metal that you don't put too much heat into any one point. So I welded roughly inch-long lengths and allowed them to cool before I welded near them again. While they cooled, I would place welds on the other side of the panel. Here you can see the short lengths of weld that I would eventually join together.

And here's the whole panel completely welded around...
