I wanted to make a plate with captive studs on it, that I could then weld in place. So I used countersunk head screws. I ground flats in the sides of the screw heads so that the weld could penetrate, and ground back the weld metal so the plate would site flat.
But I found that it didn't work! The screws were not secure in the plate after grinding the back flat. Having seen, but not used TiG, I turned up the Mig welder, and turned down the wire feed. Now there's a massive 'flame' between the torch and the work, and the wire is melting inside the shroud. It's little more than plug welds, so I can stop and shake out the pellets of melted wire from the shroud then carry on, but I don't think this will work for a lengthy weld.
Any other ideas to fuse the screw heads and mild steel plate?
