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.

It is understood that Dawei Equipment was established in September 2005 as a chemical machinery manufacturing enterprise. It then undertook a full set of chemical equipment manufacturing tasks for Yunnan Yunwei Group's 500,000 tons/year ammonia synthesis project, including gasification furnaces and high temperature and high pressure. Coal ash filters and other key coal gasification equipment. In the manufacturing process, Dawei has carried out a series of technical researches for the equipment company, and has solved the key process technologies such as coiling of thick plate cylinders, barrel pairing, and barrel welding, and pioneered the 45-degree large-angled intubation and tube. Group welding and precision control, the control board 24 group filter position accuracy control and other advanced technology. After one and a half years of hard work, in May of this year, the largest and heaviest domestic gasifiers and high-temperature and high-pressure fly ash filters have been manufactured and delivered to the installation site. It is understood that the same type of domestic equipment was previously manufactured by a machinery manufacturing company or imported from abroad. It was largely because the equipment company became the first young chemical machine company capable of manufacturing large-scale coal chemical equipment, filling the gap in equipment manufacturing in Yunnan Province at one stroke. The southwest region of China has become another equipment manufacturing base after the Northeast, Northwest, and East China.
Experts believe that the manufacturing level of the 4850 gasifier and the 6525 high-temperature high-pressure fly ash filter has reached the advanced level of similar products in the world, and has enabled the localization of key large-scale coal gasification equipment. It can completely replace imports and has broad prospects for promotion.
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.
From May 19th to 20th, a significant equipment manufacturing appraisal organized by China National Chemical Equipment Association was completed in Yunnan. After identification, various experts from China's chemical equipment manufacturing industry agreed that the 4850 gasifier and the 6525 high temperature and high pressure fly ash filter manufactured by Yunnan Dawei Chemical Equipment Manufacturing Co., Ltd. are by far the largest and most important coal chemical equipment in China. Its manufacturing technology has reached the advanced level of similar products in the world. Its successful manufacturing not only marked that the level of equipment manufacturing in Yunnan Province has been transformed from a backward province to an advanced one, but also marked a new level of independent innovation in major equipment manufacturing in China.
