The maximum thickness of the railhead that can remain after performing an Orgo Head Repair Weld is indeed 1 inch. The Orgo Head Repair Weld technique is specifically designed for repairing railheads that have experienced wear or damage. By limiting the thickness of the railhead that remains, the weld can be performed effectively, allowing for optimal penetration and fusion between the existing rail and the molten thermite material used in the welding process.

Retaining a railhead thickness of 1 inch ensures that there is enough material to support structural integrity while also allowing for an effective weld that can endure the stresses experienced by the rail. If a thicker segment were left, it might not provide the same quality of weld or structural reliability due to the potential for defects or weaknesses in the fusion zone.

This method of welding is particularly nuanced and requires adherence to specific guidelines to ensure safety and efficacy, which is why understanding the limitations of the process, such as the maximum thickness of material that can be retained, is critical for successful repairs in rail applications.
