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.

After on-site training and guidance by the leaders and experts of the manufacturers, Comrade Shen Xin organized workers to dry 4000 kg of rice on the afternoon of the same day. By 4 pm the next day, more than 10,000 kg of “rice†was dried. After the practice of the Starfire Paddle Dryer for rice harvesting and roasting by the people, the Starfire Paddle Dryer is small, efficient, and light-weight; after practice, the Starfire Paddle Dryer can bake rice in an hour 500-600 kilograms of dried rice can reach 750-900 kilograms of dry rice, and the dried rice can be temporarily stored for 1-2 months.
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
Sparks Dryer solves the urgent needs of Yongchuan's large grain producers
In the afternoon of August 21 this year, the strongest rains in the Yongchuan region since this year began to bring the comrades Shen Jing of Yongchuan District to the 10,000 kilograms of rice that is about to enter the dam. Water. As a result of continuous rain, more than 10,000 kilograms of rice will germinate and deteriorate within a few days if the problem of drying is not resolved in time. When Comrade Shen Xin was burning and when he raised his eyebrows, it was recommended by the District Promotion Station that Comrade Shen Xin immediately purchased a Chongqing Starfish Paddy Dryer.
