Toyo Tire & Rubber Co., Ltd. recently announced that its operating income for the first quarter of 2013 was 83.535 billion yen, down 30.7% year-on-year, while net profit rose sharply by 238% year-on-year to 4.234 billion yen.
Toyo Tire’s operating revenue in Japan reached 37.188 billion yen in the first quarter, down 5.4% year-on-year; operating income in the North American market plummeted 41% year-on-year to 31.062 billion yen; operating income in other markets fell 46.4% year-on-year to 15.284 billion yen. yuan.
Despite the decline in operating income, the operating profit of Dongyang Tire increased significantly in the first quarter, which was a surge of 69% year-on-year, and the operating profit rate increased from 2.9% in the same period last year to 7.1%.
The increase in operating profit was mainly attributed to the domestic business in Japan. In the first quarter, the company’s operating profit in Japan reached 6.307 billion yen, a year-on-year increase of 204%. In North America, operating profit declined slightly by 1.2% year-on-year.
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.
