A few days ago, FAW-Volkswagen Automotive Co., Ltd. filed a recall plan with the AQSIQ according to the requirements of the Regulations on the Management of Defective Automobile Product Recall, and decided to recall it from November 7, 2015 to December 3, 2016. Some of the domestic Audi Q3 models produced, a total of 55,848 vehicles.
Due to software errors in the gateway control unit during the recall, if the electronically controlled parking brake is used for emergency braking during driving, the brake light cannot be illuminated, and the rear vehicle cannot obtain the warning of the vehicle brake. Increases the risk of the vehicle being rear-ended and has potential safety hazards. FAW-Volkswagen Automotive Co., Ltd. will update the gateway control unit related software for vehicles within the scope of the recall to eliminate security risks.
FAW-Volkswagen Automotive Co., Ltd. will notify the owner of the registered letter, FAW-Volkswagen Audi franchisee will take the initiative to contact the relevant users for free maintenance. Users can also call FAW-Volkswagen Automotive Customer Service Hotline 400-817-1666 via fixed line or mobile phone. Owners can also visit the AQSIQ Defective Product Management Center website () and the WeChat public account (AQSIQDPAC) for more information. In addition, you can also call the AQSIQ Defective Product Management Center hotline to reflect problems during the implementation of the recall or submit defects.
Tungsten carbide welding bars are commonly used in the oil and gas industry for various applications. These bars are made from a combination of tungsten and carbon, which results in a very hard and wear-resistant material. Here are some specific uses of tungsten carbide welding bars in the oil and gas industry:
1. Hardfacing: Tungsten carbide welding bars are used for hardfacing applications, where a wear-resistant layer is applied to drilling tools, valves, pumps, and other equipment exposed to abrasive environments. This helps to extend the lifespan of the components and reduce maintenance costs.
2. Drill bits: Tungsten carbide welding bars are used to manufacture drill bits for oil and gas exploration. The hard and durable nature of tungsten carbide makes it ideal for drilling through tough rock formations.
3. Wear plates and liners: Tungsten carbide welding bars are used to create wear plates and liners for equipment used in oil and gas production. These plates and liners protect the underlying metal surfaces from abrasion and corrosion, ensuring the longevity of the equipment.
4. Valve seats and seals: Tungsten carbide welding bars are used to manufacture valve seats and seals for oil and gas valves. The high hardness and wear resistance of tungsten carbide ensure reliable sealing and prevent leakage in critical applications.
5. Downhole tools: Tungsten carbide welding bars are used in the manufacturing of downhole tools such as stabilizers, reamers, and drill collars. These tools are subjected to high pressures, temperatures, and abrasive conditions, and tungsten carbide helps to enhance their durability and performance.
Overall, tungsten carbide welding bars play a crucial role in the oil and gas industry by providing wear resistance, hardness, and durability to various components and equipment.
