When the fit was satisfactory, the panel was protected with HTP weld-through primer.
The panel is held in place with HTP welding magnets while the perimeter is tack-welded in with an HTP MIG-200 welder. Tack welds keep the heat down and minimize warping.
Once welded, the edges are gently ground to blend the tack welds.
The finished panel installed with no evidence of a repair.
