When cutting the rail ends in case of melting, what equipment is primarily used?

The correct choice for cutting the rail ends in the event of melting is the cutting torch. A cutting torch uses a combination of oxygen and a fuel gas to create a high-temperature flame that can efficiently cut through metal, making it particularly effective for heavy-duty applications such as rail cutting. The intense heat produced by the flame enables it to melt the rail material, allowing for clean and precise cuts.

Using a cutting torch is advantageous in terms of speed and the quality of the cut, which is essential when dealing with rail infrastructure that must maintain structural integrity and safety. This equipment is also versatile, able to cut through various thicknesses of metal with appropriate adjustments.

The other equipment, while useful in their contexts, does not match the capabilities of the cutting torch for this specific task. A flame cutter typically refers to a tool used for thermal cutting but might not provide the focused intensity needed for handling rail. An angle grinder is more suitable for grinding or cutting thinner materials and could struggle with the thickness of rail; furthermore, it does not excel in creating the clean cuts that a cutting torch does. A band saw is generally used for precise cutting of metals but is better suited for straight cuts and may not deliver the necessary heat for molten conditions effectively. Thus, the cutting
