现在激光器已是焊接和切割的工具,它也正变成可以被采用的精密处理表面的工具。能源、劳力和材料费用的增加使制造商们对激光的能力很难重视。作为热源,激光可以做到一般加热方法不能做的事情。例如,对复杂的铸件的选择区,不用对整个部件进行处理就能局部淬硬。汽车制造者在阀门座区域处对铸铁发动机头进行实验性的淬火,因此消除了座位插入。耐用的材料,诸如钨铬钴合金,可用在精确量要求的应用中,确切地说那儿必需用激光器加工。
Now that lasers are tools for welding and cutting, it is also becoming a tool that can be used to fine-tune surfaces. Increases in the cost of energy, labor and materials make it hard for manufacturers to value the power of lasers. As a heat source, lasers can do what normal heating methods can not do. For example, in the area of choice for a complex casting, the entire part can be hardened locally without treatment. The automaker experimentally hardened the cast iron engine head at the valve seat area, thereby eliminating seat insertion. Durable materials, such as stellite, can be used in applications requiring precise amounts of light, to be exact laser-machined there.
