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.

“When many companies are thinking of how to export their products to the domestic market, we see hope in exports.†Qu Bo, chairman of Qi 2 Machine Tool, said in an interview with reporters.
He told reporters that after the international financial crisis, the market structure of the domestic machine tool industry has undergone major changes, and the market demand for low-grade and small-size products has dropped significantly. While the overall demand in foreign markets has also dropped significantly, due to the price advantage of the products, Chinese machine tools have begun to enter the vision of overseas companies that have only recognized a few “world-leading machine tool industry†in the past. “Compared with products of the same level in foreign countries, our self-developed high-precision CNC floor-standing boring and milling machines and other leading products with independent intellectual property rights have entered the highest international level in terms of performance, energy saving, and intelligence, and they are One-third of the cost is cheaper. With the financial crisis, it is an excellent opportunity to enter foreign markets with price and technological advantages," he said.
In the face of the new situation in the international market under the financial crisis, Qi 2 Machine Tool, considering the long-term development of the company, made a choice different from that of most of its peers - "into overseas", and in the case of a general decline in the domestic machine tool industry, Still keeping a contrarian increase. According to statistics, from January to April, Qi'er Machine Tool achieved a total industrial output value of 970 million yuan, a year-on-year increase of 22.5%; an operating revenue of 490 million yuan, an increase of 17% year-on-year; and a profit of 30.69 million yuan, a year-on-year increase of 7.4%.
What are the reasons for the steady growth in exports of Qi Machine Tools? The reporter found that, unlike low-tech export products without technical content, the products of Qi 2 Machine Tool are behind strong scientific research capabilities. They aimed at the world's high-end technology, constantly through independent innovation, R & D to fill in blank new products, making Qi 2 successfully developed and based on overseas markets.
As the production base of heavy-duty machine tools and forging equipment in China, Qi 2 Machine Tool is the national key support enterprise for the development of CNC machine tools in the national “Eleventh Five-Year Planâ€. The company focuses on the defense industry, large aircraft, moon landing project, ship manufacturing, nuclear power, Wind power, transportation and other fields develop various urgently needed major equipment. Since the beginning of this year, the company has successively developed seven types of domestically-produced CNC type floor-standing milling and boring machines, 320 large-scale circular welding machines for large-scale aluminum ingots, CNC gantry wire feeders, and CNC laminating machines. Taiwan (sets) new products.
"In times of crisis, it is important for companies to have strong R&D capabilities and have their own unique products. At the moment, we have given up products that compete too much with foreign manufacturers and specialize in our own unique products. For example, the heavy-duty gantry type five-axis mixing The joint machine tool is a new product jointly developed by us and Tsinghua University, and although the economic situation is not good, the order volume of this product has increased greatly, and the original price has been maintained, and the profit is also relatively high in our products. Qu Bo said.
A steady stream of innovative products have enabled Qi 2 Machine Tool to achieve continuous success in the international market. In 2007, at the 17th European Machine Tool Exhibition in Hanover, Germany, the world's largest machine tool exhibition, the company signed 20 vertical lathe products in one fell swoop, and the products entered the European market for the first time. Not long ago, after participating in the tendering project for the heavy-duty CNC milling and boring machine of India State Power Corporation, the company eliminated the world machine tool companies Insel, Parma and Czech Skoda with excellent cost performance after three rounds of selection. Winning the bid in one fell swoop, achieving a new breakthrough.
Looking back at the path that the company has taken in the past six months, Qu Bo has deep feelings: “As long as we always target the world’s cutting-edge technologies and insist on independent innovation, we will continue to introduce products with independent intellectual property rights and fill the gaps at home and abroad. No crisis will stop the 'made in China'. 'Step to the world!'
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
As overseas demand has decreased and exports have become more difficult, many Chinese manufacturing peers have “turned their bows†and the export-oriented and domestic-selling business strategies have changed. Under the general trend of shifting the export-oriented and domestic-selling business strategies, China’s heavy machine tool production base, Qiqihar No. 2 Machine Tool Group, has "Reverse the boat", taking advantage of foreigners' increasing sensitivity to product prices under affluent conditions, seizing the opportunity to actively research and develop independent brand products with high technological content and low prices, boldly marching into overseas markets and turning crises into opportunities. A new path of “increase domestic sales by export†has been created.
