在大功率激光焊接设备中,二氧化碳激光器(CO_2激光器)最常用。这种激光器发出光的波长为10.6 μm。CO_2激光器的混合气体主要是氦(保证产生热量的移动传输)、二氧化碳(激光活性介质)和氮(气体放电产生激发所必需的能量)。CO_2激光器在用于薄壁结构的高速焊接时,成本效益尤其突出,例如轿车车身的焊接。这种类型激光器的缺点是需要一个非常复杂精巧的系统将激光束发送到工件上。这也就意味着这套系统的工作平台缺乏灵活性,如果需要经过很多反光镜来
In high-power laser welding equipment, carbon dioxide laser (CO2 laser) the most commonly used. The wavelength of light emitted by this laser is 10.6 μm. The CO 2 laser gas mixture is mainly composed of helium (to ensure the transfer of heat generated), carbon dioxide (laser-active medium) and nitrogen (energy necessary for gas discharge to generate excitation). CO 2 lasers are particularly cost-effective when used for high-speed welding of thin-walled structures such as welding of sedan bodies. The disadvantage of this type of laser is that it requires a very sophisticated system to send the laser beam to the workpiece. This also means that the system platform lack of flexibility, if you need to go through a lot of mirrors
