Xinhua Changchun, April 11th (Reporter Zhang Yi and Du Xuejing) With the rapid development of China's auto industry, a relatively complete auto parts industry has taken shape. Many multinational auto groups are now including China in their global supply chain of auto parts. As the world’s largest auto multinational company has entered China, almost all the world’s leading auto parts manufacturers have come to China to invest in factories or establish technical cooperation with domestic parts factories. At present, 1,200 of the 5,000 auto parts companies in the country are foreign-invested enterprises. The purpose of these multinational companies' production in China is not only to occupy the Chinese market, but also to make China one of the global production bases and supply them to production plants or parts factories around the world. At the same time, China's private auto parts enterprises have developed rapidly. A group of automotive and component companies with high technological content, good efficiency, and large scale have gradually grown up. The gap between China's automobile and parts industry and the international level has been greatly reduced, and a certain competitive automobile and parts manufacturing system has been initially formed. Since the reform and opening up, along with the rapid economic development, China's auto industry has made remarkable achievements, and the auto parts industry has also made considerable progress. Not only has it met the needs of the domestic market, some auto and parts products have entered the international market. At the same time, China's auto parts industry has a certain production capacity and technical capabilities, and has competitive advantages in the production of some parts and components. Some of these parts and components products have been recognized by multinational companies and have greater export potential. Wei Jianguo, vice minister of the Ministry of Commerce and director of the National Electromechanical Products Import and Export Office, said that the state will adopt seven measures to expand the export of automobiles and parts: First, to support domestic auto and parts companies to become bigger and stronger. The second is to use the globalization strategy of multinational companies to develop China's auto and component manufacturing capabilities. The third is to accelerate the construction of auto and auto parts export bases. The fourth is to increase policy support for the export of automobiles and components. The fifth is to promote and support enterprises through various international certifications. Sixth, it is to improve the export service system for automobiles and components. Seventh, standardize export order and curb price wars in overseas markets. (Finish)
Nickel-based alloy powders are commonly used in plasma transfer arc welding (PTAW) due to their excellent corrosion resistance, high temperature strength, and good weldability. These alloys are typically composed of nickel as the base metal, with various alloying elements added to enhance specific properties.
Some commonly used nickel-based alloy powders for PTAW include:
1. Inconel 625: This alloy powder is widely used for PTAW due to its high strength, excellent resistance to corrosion, and oxidation at elevated temperatures. It is commonly used in applications involving seawater, chemical processing, and aerospace industries.
2. Hastelloy X: This alloy powder is known for its high-temperature strength and oxidation resistance. It is commonly used in applications involving gas turbine engines, industrial furnace components, and chemical processing.
3. Monel 400: This alloy powder is known for its excellent resistance to corrosion, particularly in marine environments. It is commonly used in applications involving seawater, chemical processing, and oil refining.
4. Inconel 718: This alloy powder is known for its high strength, excellent resistance to corrosion, and good weldability. It is commonly used in applications involving aerospace, oil and gas, and nuclear industries.
5. Inconel 601: This alloy powder is known for its excellent resistance to high-temperature oxidation and corrosion. It is commonly used in applications involving heat treatment equipment, chemical processing, and power generation.
These nickel-based alloy powders can be used in PTAW processes to create high-quality welds with excellent mechanical properties and resistance to corrosion and high temperatures.
