In the first step, due to the shape of the casting, a feasibility study had to be carried out – for this purpose, a 3D scan of the flanges was performed, with a particular focus on the radii of the transition to the casing area. The result is a three-dimensional model of the casing’s fragment within the area of planned upgrade. On the same […]
