Looking pretty good. A method to avoid warping when welding is to make short welds and let the piece cool in between each weld. Minimizing the heat input to any one area is key, while maintaining the overall part temperature stable (between 120 and 150F) during welding is very important. Preheat of the entire part is useful to maintain dimensional stability during welding.
