激光在汽车工业中的典型应用激光除用于国防、医学和物理学本身外,实际上它的很多用处在于工业应用方面。激光具有亮度高(比太阳表面也要高出200多亿倍)和方向性、单色性好四大特点,激光束经聚焦后可获得极高的能量密度(108～1013w/cm2),足以把最难熔的材料在短时间内汽化,因此激光成了一种极其锋利的加工工具,几乎可以加工任何材料。激光光斑可聚焦到微米级,输出功率可调节,可实现精密微细加工。由于激光加工属非接触加工,无明显机械力和工具损耗问题,加工速度快,热影响区小,且激光加工中无需切削液,躁声
Typical applications of lasers in the automotive industry In addition to their use in defense, medicine and physics, lasers are useful in many industrial applications. Laser with high brightness (more than 200 billion times higher than the sun surface) and the direction of the monochromatic good four characteristics of the laser beam can be obtained after focusing high energy density (108 ~ 1013w / cm2), enough The hardest material is vaporized in a short period of time, so the laser becomes an extremely sharp machining tool that can process almost any material. Laser spot can be focused to the micron level, the output power can be adjusted, enabling precision microfabrication. Because the laser processing is non-contact processing, no obvious mechanical force and tool wear problems, processing speed, heat-affected zone is small, and the laser processing without cutting fluid, noise
