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.

Deputy Secretary-General Hu Qianlin, who is in charge of scientific and technological work at the Petrochemical Association, introduced that in recent years the overall technical level of China's petroleum and chemical industries has been significantly improved, but there are still serious shortcomings in supporting the development of the industry. The concrete manifestations are the basic research of the industry and the development of common technologies. The power is not enough, the project's ability to transform the results is weak, new product development has not really escaped from tracking imitation, energy-saving environmental protection technology development is lagging behind, and the level of equipment and automation are still low. At present, technology needs to be supported as it optimizes product structure, promotes industrial upgrading, and breaks through resource constraints.
It is understood that the "10+2" key areas identified in the "Opinions" include 10 major industries and two public areas. Among them, the top 10 industries are oil and gas exploration and development, petroleum refining, petrochemicals, chemical fertilizers, pesticides, rubber processing, new coal chemical industry, chlor-alkali, chemical new materials, and fine chemicals. The two public sectors are chemical equipment and environmental protection. The 130 supporting technologies identified in turn fall into two broad categories, including 58 advanced and mature technologies that need to be vigorously promoted, and 72 technologies that need to be developed with large industrial correlation, good market prospects, and are not yet perfect.
Hu Qianlin told CCIN reporters that the implementation of the "opinions" requires a clear three major directions: First, to adjust the product structure, and strive to improve the performance of chemical materials, accelerate the refinement of products, specialization and green; Second, to promote energy-saving emission reduction , vigorously develop new energy-saving technologies, energy recovery technologies, cleaner production technologies and development process enhancement technologies, etc.; third is to break through resource constraints and actively develop alternative chemical technology routes for petroleum represented by new types of coal chemical, biochemical, etc. to increase sulfur and phosphorus The recovery of chemical mineral resources.
He pointed out that it is necessary to make full use of the timing of industrial adjustment and revitalization, and concentrate on promoting a group of advanced and applicable technologies with mature technologies and rapid results; after the breakthroughs in technological R&D and engineering research, active demonstration projects are launched to effectively promote the petrochemical industry. Development; breaking through a batch of key technologies and common technologies, focusing on solving some of the technological bottlenecks in industrial development; while relying on major petrochemical engineering projects to develop a number of major complete sets of equipment.
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
In order to give full play to the important supporting role of science and technology in maintaining growth, expanding domestic demand, and adjusting the structure, the China Petroleum and Chemical Industry Association released the “Guiding Opinion on the Revitalization and Support of Petroleum and Chemical Industry Industry†in Beijing on October 20, confirming the industrial rejuvenation. The "10+2" key areas and 130 supporting technologies. The "opinions" will provide strong technical support for structural adjustment and industrial rejuvenation of the petroleum and chemical industries, and provide a solid technical foundation for the industry to take a new path of industrialization and healthy and sustainable development.
