This spring, the concern "along the way" planning release. Infrastructure interoperability is a priority area "along the way" construction, mature Chinese high-speed rail technology in which shine again. Laser processing technology is the track manufacturing industry in recent years the most important method of manufacturing techniques, to enhance the rail manufacturing process plays a great role. The rapid development of China's high-speed rail, but also for laser processing to provide a huge market of potential applications, laser cutting cutting and welding technology will also track vehicle manufacturing technology to a new era. Global high-speed rail plan more than 43,000 kilometers, built more than 28,000 km high-speed rail. Only the Southeast Asian market rail project with a total investment will be close to 980 billion yuan, the Asian investment bank to support the Asian Infrastructure Development Fund, the BRIC Development Fund and other financial investments, the demand for quick release. Along the way to continue to promote, only Asia-Pacific rail project planning a total investment of close to 1 trillion yuan; and Thailand have signed a high-speed rail cooperation agreement, the old railway is stepping forward. China is willing to actively participate in the new high-speed rail horse bid. In the area of ??strategic push all the way, it is expected to accelerate the pace of China's railway to the sea. At present, China is facing the development of rail transport high-speed buses, metro buses, light rail vehicles and high-speed heavy trucks, train weight is to increase train speed preferred conditions. Aluminum is light weight, corrosion resistance, good appearance flatness, easy to manufacture complex surfaces and high strength ratio, can reduce weight reduced running resistance, reduce energy consumption, increase the load, and therefore in the world railway transportation has been develop. Body, bogie, as a key component of the high-speed train on its quality affects the entire high-speed train safety. With the rapid development of China's high-speed railway, the body materials are also developed from common alloy steel to stainless steel and aluminum profiles. Change material, naturally led to improved processing technology, laser cutting, laser welding of advanced technology also will be introduced to the production line railway vehicle.
