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.

In the measurement phase of the temperature and humidity monitor, the SCM sends a temperature and humidity measurement command to the temperature and humidity sensor every 10 seconds, and receives the raw temperature and humidity data of the output and sends it to the data storage chip for temporary storage. When the query subroutine queries the measurement time, the temperature and humidity data measurement is stopped. After the measuring body is to be taken out, it is connected to the host computer through the RS-232 serial communication interface so that it enters the data transmission mode.
The PC on which the baking system software is located has master control of the serial transmission bus. The temperature and humidity monitor measures the body as a slave and responds to the host's various commands. First, the host sends a data transfer instruction to the slave as a sender and the slave accepts the transfer instruction as a receiver. Second, the slave and the sender send data to the serial bus. The host reads the data from the serial bus as a receiver. data.
Because the original data of temperature and humidity received is in the form of binary, and it has certain dependence on the power supply voltage and measurement accuracy of the sensor, the software of the baking and drying system performed by the temperature and humidity monitor needs further correction and conversion. The final temperature and humidity data are obtained. The final temperature and humidity data will be stored in the form of a file on the host computer, which can be printed, moved, and stored at any time.
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.
Application of Temperature and Humidity Monitor in Drying System
With the development of modern science and technology, more and more scientific and technological instruments have replaced artificial applications in agricultural cultivation, especially in greenhouses. For example, the use of temperature and humidity monitors is a common one. The application of this instrument from the simple sensor design in the past to the application of a modern single-chip computer has resulted in better measurement accuracy.
