Where should the Boutet diverting plug be dried during preheat?

The Boutet diverting plug should be dried on the non-pour side during preheat because this practice helps to ensure that the plug maintains its integrity and functionality during the welding process. When the diverting plug is on the non-pour side, it is kept away from direct exposure to molten material, which can lead to contamination or affect its structural properties. Preheating the non-pour side also aids in effectively removing any moisture, which is crucial for preventing steam generation during the heating process that could interfere with the quality of the weld.

Drying the plug in this specific location enhances the overall effectiveness of the thermite welding process by minimizing the risk of defects related to moisture, ensuring a clean, effective weld joint. This approach aligns with best practices in thermite welding, where maintaining appropriate temperatures and conditions is essential for achieving strong, reliable welds.
