What is the first step for cutting rail using an oxyfuel torch?

When cutting rail using an oxyfuel torch, the first step is to remove a small section of the rail head. This step is crucial because it allows for easier access to the rail and prepares the material for a more effective and cleaner cut. By removing this portion, you ensure that the cutting process can be executed more smoothly, as it avoids complications that may arise from cutting through the full thickness of the rail, which can lead to uneven cuts or other issues.

By starting with the rail head, you create a point of entry for the torch, enabling you to set your cutting process in motion without significant resistance. This technique is essential in thermite welding and rail cutting practices, as it directly influences the quality and precision of the cut being made. Proper preparation is a key element in successful oxyfuel cutting, and handling the rail head first lays a solid groundwork for the overall operation.
