Duratop cultivator sweeps Welding and widia Duratop cultivator sweeps, is the result of a mixture of the best materials Bellota already utilizes with special new anti-wear carbon based materials, which, together with complex controlled industrial joining processes, converts them into more robust and very long lasting pieces of cultivator sweeps. The industrial process guarantees optimum hardness of both the base material and the added material, making it possible to offer a product with a minimum wear in the zones joining both materials, thus making them even more durable. The process of joining the disc to the base piece with the most advanced technology, called Brazing, guarantees a long life of the Duratop cultivator sweeps, which, depending on terrain conditions, can be up to 10 times longer than conventional pieces. The Duratop cultivator sweeps series are based on two different processes: 1) Contributions: The critical work zones of each cultivator sweeps are studied in detail and high wear-resistant material is added with complex and controlled industrial welding processes according to the work demands each piece is going to bear. 2) Widia: The tungsten-carbide inserts on the cultivator sweeps, have optimum wear- durability - tenacity performance to endure the severest work conditions.
