Iron-based alloy powder is commonly used in plasma transfer arc welding (PTAW) due to its excellent mechanical properties and high resistance to corrosion and heat. This type of powder is typically composed of iron as the base metal, along with various alloying elements such as nickel, chromium, molybdenum, and tungsten.

The equipment has been completed in the pilot test of WISCO coking company. The results show that the wastewater treatment effect is good, the operation process is stable, and the operation cost is low. As tested by the Hubei Provincial Environmental Protection Agency, the high concentration of ammonia nitrogen in the coking industrial wastewater treatment efficiency reached over 70%.
The specific composition of the iron-based alloy powder may vary depending on the desired properties and application requirements. For example, adding nickel can increase the strength and toughness of the weld, while chromium enhances the corrosion resistance. Molybdenum and tungsten are often added to improve the high-temperature strength and creep resistance of the weld.
Iron-based alloy powders for PTAW are available in various particle sizes, typically ranging from a few micrometers to several hundred micrometers. The powder is usually fed into the plasma arc through a powder feeder, which ensures a controlled and consistent supply of powder during the welding process.
During PTAW, the powder is melted and deposited onto the workpiece, forming a weld bead. The high energy plasma arc provides the heat necessary to melt the powder and the base metal, creating a strong and durable weld joint.
Overall, iron-based alloy powder for plasma transfer arc welding offers excellent weldability, high mechanical properties, and resistance to corrosion and heat, making it suitable for a wide range of applications in industries such as aerospace, automotive, and power generation.
The high concentration ammonia nitrogen industrial wastewater microwave treatment unit jointly developed by Wuhan Mayflower Environmental Protection Technology Co., Ltd., Huazhong University of Science and Technology and Wuhan Iron and Steel Group Co., Ltd. passed the expert appraisal on January 18th. The successful development of this equipment will effectively solve the high cost of high-concentration ammonia nitrogen wastewater treatment in China's steel, coking, chemical, pharmaceutical and other industries.
