That looks good ,but the only thing I would do different is to do half inc stitch welds with half in gaps between the welds. I think it will actually be stronger as the welds will hold it in place and the unwelded areas will be stronger. When you weld sheet metal the weld is strong but it actually makes the metal next to the weld the weak point. The only place you will find a continuous weld in factory construction in a boxed frame section.
