Wison Engineering (China) Co., Ltd. announced that its consortium with South Korea’s Dalin Engineering Co., Ltd. has signed an EPsCm (design, procurement service) with BASF Polyurethanes (Chongqing) Co., Ltd. on the Chongqing 400,000-ton MDI integration project in Shanghai. , construction management) contract. The signing of the contract announced that the world's largest MDI monomer project is about to start. The signing project is a joint implementation of the general contracting service contract by Wison Engineering Co., Ltd. and Korea Dalin Engineering Co., Ltd. to jointly undertake the detailed design, procurement and construction management of the project. It is reported that the three parties have planned to concentrate on office work and hold a project kick-off meeting at the Wison headquarters on June 1. In cooperation with BASF, Wison will establish an excellent project management team to conduct comprehensive monitoring and scientific management of the project implementation process, and strictly implement the owners' high standards for project safety, environmental protection and quality in strict accordance with relevant national regulations. On-time delivery of quality projects. The 400,000-ton MDI project was independently invested by BASF about RMB 8 billion, including the MDI production facility, nitrobenzene production facility and aniline production facility. It is the core part of the integrated chemical production complex in Chongqing Changshou Economic and Technological Development Zone. This facility will be mainly used for the production of core raw materials for polyurethane foams after its operation in 2014, which will enable Chongqing to become a world-class polyurethane raw material production base and a polyurethane product technical service center in the western region. 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 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.
