Re: Butt welds for patch panels

Thanks Greg!


Progress on the hood, the bead details in the brace are offset on the ends to match the hood opening flange. So we use a Vernier protractor to find the angle, and transfer that to our panel. This is where the transition of the taper starts..





Once tapered, the excess is removed from the bottom side and the outer seams TIG welded in place.





A piece of round stock has a radius added to serve as a hammer form for the beads. They are hammered around and excess removed from the back side..





A piece of 16 gauge cold rolled steel is trimmed to fit and TIG welded in place.








Welds dressed and media blasted..





The bend line is transposed from the original. As this bend is slightly convex, it was started using a tipping wheel on the bead roller to a 45* angle, and then finished on the mag brake.











A reminder of the carnage we are repairing:
