As the surface finish and processing dimensional tolerance of tungsten carbide can meet the use of mechanical seal wear-resistant parts, and its physical property indicators determine it is suitable for seismic and shock absorption material requirements The improvement of tool material performance can promote production efficiency, improve the use requirements of production equipment, cemented carbide has good physical stability performance then it is a tool material widely used in industrial.
During cemented carbide welding, the following points shall be paid attention to: 1. Cemented carbide is a kind of powder metallurgy sintering product with high hardness. When welding, try to use fire to directly burn the cemented carbide, which is easy to crack. 2. In order not to overheat, the cemented carbide can be welded. The melting point of silver is larger than that of copper, which reduces the heating of cemented carbide. 3. In cold weather, it is better to use quicklime for heat preservation of welded carbide products. During welding, the carbide is heated violently. Once the heating stops, the cemented carbide cools again, leading to cracking of cemented carbide. 4. For the strong welding of cemented carbide, try to put some flux first.
Most people will confuse tungsten and tungsten carbide, as tungsten carbide is the most widely understood form of tungsten available. However, there are some niche use cases for its pure form, and this section will contrast tungsten and tungsten carbide to illustrate how they differ. Below, in Table 1, is shown several mechanical properties of each material, and their comparison should give readers a better idea as to when to implement one material over the other. Note that tungsten carbide (WC) is used for this comparison, but more alloys exist.
