The AT welding process brings its own set of challenges, as extremely high temperatures are involved during the process and an opaque welding setup, the visual acquisition of the physical process to understand the flow field and the solid-liquid phase change of the rails inside the casting system, is inherently difficult to observe in real-time. Thus, in this chapter, experimental trials are conducted to indirectly validate the developed numerical model discussed in Chap. 3 for predicting the flow field and solid-liquid phase changing within the mould during the pouring stage of the AT welding processAluminothermic (AT) welding.
