Narrow slivers are the hardest to repair as it concentrates the heat in such a confined area, adding to distortion and shrinking issues. For any such future work I would suggest a wider, parallel gap with a radius at the end. The wider the better, for separating the heat affected zones. Position seams where better access for planishing the welds exists..

For that damage, given adequate access from the back, I would have considered making one large patch to span the two slices, cutting out the center, using a radius at the end. This would give you two horizontal weld passes vs. the four that you used. Less welds, less distortion.
