“Extremely, on the Central Plains Road, there are actually things in the trunk of the tree in the trunk of the tree.” Yesterday, the citizen Mr. Wu reported to the newspaper’s hotline that the two trees were older on the sidewalk 100 meters west of the intersection of Zhongyuan Road and Songshan Road. The large hollow trunk of Fatong was bricked and cemented. "Isn't it cruel? Will the tree die?"
At noon yesterday, the reporter came to the scene. On the north sidewalk of Zhongyuan Road, he saw an old tree with a diameter of about 80 centimeters. It was necessary to visually measure the big tree to be able to hold two people. The trunk of this tree has a large hollow area. The cement wall filled in the trunk is more than 2 meters high, and the width of the root is about 40 centimeters. Continue to the west, and there is a stone brick in the trunk of Fartung tree that is built from top to bottom.
In response, Wang Xihong, head of the Central Plains Greening Team of the Zhengzhou Municipal Bureau of Parks, said that after the trees on the street were infested, some insecticides were added to the cement and landfilled in areas where trees were hollowed by insects to prevent rainwater from entering and Pests and diseases continue to erode large trees, which will effectively protect trees. "Some trees' wounds" are not necessarily due to insect infestations. For example, normal growth cracks, old tree trunks are hollow, and timely filling of tree hollows is actually a protective measure for trees."

Iron Based Alloy Powder

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.
