China Rubber Association participated in the Ministry of Commerce's two-standard revision of tire distribution
Recently, the General Office of the Ministry of Commerce has issued the “Circular on Distributing the First Batch of Circulation Industry Standard Project Plans in 2012†[Business Circulation Letter [2012] No. 195]. The notice requires that the 48th item of the project approves the development of the "Tire Claims Appraisal Staff's Professional and Technical Requirements" as the recommended standard, and the 49th item approves the revision of the " Tire Distribution Company's Business Code (Claims Requirements)" as mandatory standards. Both standards are made by China Rubber. The Industrial Association and the Business Technology Quality Center are responsible for organizing drafting, formulation, and revision. In accordance with the requirements of the Ministry of Commerce, in order to fully absorb and learn from international standards and foreign advanced standards, and closely link with existing national standards and industry standards of tires, and enhance the applicability, effectiveness and advancement of the standards, the China Rubber Association and Commerce Technology Center decided to establish The drafting group hopes that the relevant member units and the people concerned with the development of the tire industry in the society will actively participate in this work. It is understood that on September 27, 2008, the Ministry of Commerce issued the "SB/T10468.2-2008 tire distribution companies operating standards claims requirements" recommended standards. After the standard was released, it was supported by a large number of manufacturers, distributors, and users/consumers. It also contained restrictions on the sale of smuggled tires, trademark tires, non-implementation of "Three Guarantees" service tires and counterfeit and inferior tires in the industry. Pre-sales, sales, and after-sales service quality have been improved, and in particular, guidance has been given to the tires after-sales claims management service, which has achieved certain results in promoting the healthy and orderly development of the entire tire marketing market. On this basis, in order to better serve tire manufacturers, tire dealers, users/consumers, and promote the healthy development of the industry, according to the implementation of the "SB/T10468.2-2008 Tire Distribution Company's Operational Management Claims Requirements" for three years As for the characteristics of the national legal system, we now propose to upgrade the "SB/T10468.2-2008 Tire Distribution Company's Operational Regulation Claims Requirements" to the level of technical regulations, which will be raised from the recommended standards to mandatory standards and become technical regulations. This will surely curb the unfair competition in the production and marketing of non-“three guarantees†tires and other illegal and unethical behaviors, protect market fairness and fair competition, protect the legitimate rights and interests of tire manufacturers, distributors, users and consumers, and further promote tire marketing. The market is healthy, scientific, and orderly. At the same time, in order to form a systematic tire marketing management system and standardize the service behavior of personnel in the industry, it also proposed to formulate a recommended standard “Professional Technical Requirements for Tire Claims Appraisers†in order to match the technical documentation and technical regulations of tire circulation industry standards. Implementation. Cobalt-based alloy powders are commonly used in plasma transfer arc welding (PTAW) due to their excellent high-temperature properties and resistance to wear and corrosion. These alloys are typically composed of cobalt as the base metal, with various alloying elements such as chromium, tungsten, nickel, and carbon added to enhance specific properties.

The use of cobalt-based alloy powders in PTAW offers several advantages, including:
1. High-temperature strength: Cobalt-based alloys exhibit excellent strength and resistance to deformation at elevated temperatures, making them suitable for welding applications that involve high heat.
2. Wear resistance: These alloys have a high hardness and resistance to wear, making them ideal for welding applications where the welded parts are subjected to abrasive or erosive conditions.
3. Corrosion resistance: Cobalt-based alloys offer good resistance to corrosion, making them suitable for welding applications in aggressive environments, such as those involving chemicals or saltwater.
4. Thermal conductivity: Cobalt-based alloys have good thermal conductivity, allowing for efficient heat transfer during welding and reducing the risk of heat-affected zone (HAZ) defects.
5. Compatibility with other materials: Cobalt-based alloys can be easily welded to a wide range of base metals, including stainless steels, nickel alloys, and other cobalt-based alloys, providing versatility in welding applications.
To use cobalt-based alloy powders for PTAW, the powder is typically fed into the plasma arc using a powder feeder. The powder is then melted by the high-temperature plasma arc and deposited onto the workpiece, forming a weld bead. The specific welding parameters, such as arc current, travel speed, and powder feed rate, will depend on the specific alloy and application requirements.
It is important to note that the selection of the cobalt-based alloy powder should be based on the specific welding application and the desired properties of the final weld. Different cobalt-based a
