Thermite Welding Supplies.Luting sand is a mixture of refractory materials used in thermit welding to seal the gap between the rail ends to be joined. The luting sand forms a temporary mold or container around the weld site, preventing the molten metal from escaping and ensuring that the weld solidifies correctly.The advantages of using luting sand in thermit welding are:

Provides a proper seal: The luting sand is placed around the rail ends and provides a seal, ensuring that the molten metal does not escape during the welding process. This results in a more precise and uniform weld.

Resistant to high temperatures: Luting sand is made of refractory materials, making it resistant to high temperatures of up to 2000°C, ensuring that it does not melt or burn during the welding process.

Easy to handle: Luting sand is a dry mixture, making it easy to handle and apply to the rail ends, allowing for precise application and reducing the risk of spills.

Economical: Luting sand is a cost-effective option for thermit welding, as it is relatively inexpensive compared to other welding materials.

Non-toxic: Luting sand is non-toxic, making it safe for the environment and the welders.

In summary, luting sand plays a critical role in thermit welding by providing a seal around the rail ends, ensuring that the molten metal does not escape during the welding process. Its advantages include providing a proper seal, resistance to high temperatures, ease of handling, cost-effectiveness, and non-toxicity.
