As the country's key industry in the field of digital economy and intelligent manufacturing, the rail transportation sector accounts for the largest scale of new infrastructure investment during 2020-2025, which is expected to reach 344,000,000,000,000. In recent years, with the transformation of China's railroad lines and capacity demand, the domestic railroad rolling stock into a period of rapid renewal, reached 153.8 billion yuan in 2015, is expected to "13th Five-Year Plan" period of investment in railroad rolling stock for about 800 billion yuan, and will continue to maintain the upward trend.
Laser processing technology as one of the core technologies, in the field of rail transportation has a variety of applications, such as laser guidance, positioning, ranging, welding, welding, cladding, cutting and so on. And laser cleaning has also become a popular application in rail transportation manufacturing in recent years due to its advantages of green environmental protection, high efficiency and energy saving, and has received high attention from the industry.
Many mature application cases of laser cleaning in the field of rail transportation include: car skin paint removal; wheel to axle cleaning; railway track rust removal; cleaning before flaw detection (signal conduction, flaw detection, paint removal, rust removal); aluminum alloy workpiece pre-weld cleaning; bogie post-weld cleaning; gearbox cleaning and other cleaning programs, involving the production of parts and components, the entire car manufacturing, maintenance and repair and replacement of many aspects.
The laser cleaning of wheelset axle significantly shortens the cleaning time; the layered cleaning before flaw detection meets the different maintenance requirements; the aluminum alloy pre-welding cleaning improves the tensile strength by 6%-9%; and the skin paint removal can save 30%-50% of the cost. Dr. Jin believes that: laser cleaning as an emerging industrial cleaning technology, can do the traditional dry ice, sand blasting or chemical wet cleaning can not do a number of indicators: such as micron-level cleaning accuracy, the minimum degree of damage to the substrate and modification, Sa3.0 degree of cleanliness, the whole process of visual and controllable, non-consumable and non-polluting, etc., and is now gradually forming a substitute for the traditional cleaning methods in the domestic market will continue to expand the market share.
Laser as an important manufacturing technology method, how to turn scientific research results into industrial applications is a national concern. Technology-driven enterprises play an irreplaceable role in accelerating the application and transformation of new processes. Taking this summit as an opportunity, Water Drop Laser insists on scientific and technological innovation as a new engine and source of power for enterprise development, and will continue to provide more accurate and effective products and solutions for the rail transportation industry, lead the industry in innovation and change, and help China Smart Manufacturing 2025.
