Tungsten carbide welded stone-cutting blades use tungsten carbide cemented carbide as the cutting part, which is fixed on the substrate through a welding process. Leveraging the high hardness and wear resistance of tungsten carbide, they are suitable for scenarios like stone extraction and processing. The welding ensures structural strength, helping to handle the impact and load during cutting. They can be cleaned and re – sharpened to extend service life, and are common tools in the stone – cutting process.
