The experts will now say, ah yes, no news, only basics. But still if not new for me, I forgot a lot and had to call back to my mind.
First my friend told me to use the body file for identification of uneven spots. See pics one and three above this article. The marked areas (e.g. yellow circle and black arrows) are too low, need to be planished from back side. If you did not work accurate enough before, which is the case with the shown part, insanity will spread in your brain.
Second, trim the two panels so that they fit without gap. Easily said! I paid very much attention to this point, when trimming the upper lip and the main panel, also avoided corners, cut round curves instead. (see pic).
Weld without rod, avoid additional material by all means! Weld in short sections (i went for 5 to 10 cms) and rectify these sections immediately while the material is still hot.
My intellect absorbed these hints like a sponge and then I started putting the two pieces together. Spot welded them first (made first mistake I think, should have made more spots).
At the beginning it worked as it should, I interrupted welding and hammered the seam, resulting an an even distortionfree area. But after about half the distance, I lost track. Instead of flowing together the two edges starting moving away from each other as soon as I approached the flame to them. Had to stop in short intervals to hammer the edges in position again and had to use some wire to fill. Finally the result was still quite a progress compared to other welds I have made, but it is not totally clear to me why the second half of the weld caused so many problems. Maybe my concentration went down, and I missed the perfect position of the welder, I don´t know.
