I posted this on a previous post, but never got any responses. This is a process listed on the Eastwood site under "Tips". This involves an original body seam where the seam has been factory spot welded in the flange of a seam. The two pieces of sheet metal being joined are flanged 90 degrees to the two pieces of sheet metal being joined, spot welded, then seam sealed.
In the article, it recommends wire brushing out the seam sealer and getting to bare metal. Then a tig filling rod the diameter equal to just under the depth of the seam is laid in the seam. With a mig welder set "hotter" than the thickness of the sheet metal being joined, you spot the rod in the seam. Then you come back over the seam and fill in with weld. The idea is to melt the tig rod into the seam with the mig filler wire, closing the seam. I have never came across this idea or heard of anyone using it. Not sure what the reason for using Tig filler rod with Mig wire would benefit. Just looking for opinions.
