Recently, Shanxi Provincial Department of Science and Technology and Datong Municipal Bureau of Science and Technology organized an expert acceptance of the Shanxi Province Science and Technology Innovation Project “ Sino Heavy Industry Commercial Vehicle Automatic Transmission (AMT) Development†undertaken by China National Heavy Duty Truck Corporation, and the participating experts heard the project report. After reviewing relevant materials, they passed the acceptance after questioning and discussion.
China National Heavy Duty Truck AMT Transmission
This project achieved the independent development of heavy-duty commercial vehicle automatic transmissions (AMT), key technologies such as intelligent shift regulations, complete and thorough implementation of V-cycle development process, AMT industrialization, clutch actuators, matching and calibration technologies, etc. A breakthrough was achieved. The first round of prototype production of the project has been completed. At present, the second round of prototype rig test and preliminary reliability test are in progress. The project has applied for 9 patents, including 3 invention patents and 6 utility model patents. It has authorized 3 utility model patents.
Tungsten carbide welding rope is a type of welding filler material that is used for hardfacing applications. It is made by combining tungsten carbide particles with a binding material, such as nickel or cobalt, to create a rope-like form.
Tungsten carbide is known for its exceptional hardness and wear resistance, making it ideal for applications where the welded surface needs to withstand extreme abrasion and impact. The welding rope is typically used in industries such as mining, oil and gas, construction, and agriculture.
When the tungsten carbide welding rope is heated during the welding process, the binding material melts and fuses the tungsten carbide particles to the base metal, creating a hard and durable surface. This helps to extend the lifespan of equipment and machinery by protecting it from wear and tear.
Tungsten carbide welding rope can be applied using various welding processes, including manual metal arc welding (MMA), gas tungsten arc welding (GTAW), and flux-cored arc welding (FCAW). The choice of welding process depends on the specific application and the equipment available.
Overall, tungsten carbide welding rope offers a cost-effective solution for protecting and repairing high-wear surfaces, making it a popular choice in industries where durability and longevity are essential.
