美食品机械(FMC)公司北方军械部所属的一家工厂使用一台大功率CO_2激光器代替埋弧焊焊接导弹发射架的发射导轨,在时间和生产费用方面实现了重大的节约。这是一台AVCO Everett连续波CO_2激光器,可向工件输出15千瓦的功率,其中85％左右的功率集中在直径工毫米的光束內。导轨的22毫米厚1015碳钢板对接接头,以前用埋弧焊焊接,每条焊縫需要在正面焊七道,铲背后还要另外再焊一道,因而费工费时。改用激光焊之后,每条縫
A plant belonging to the Northern Ordnance Department of the Food Machinery (FMC) Company, which uses a high-power CO2 laser instead of the launch rail of a submerged-arc welded missile launcher, has realized major savings in terms of time and production costs. This is an AVCO Everett CW CO2 laser that delivers 15 kW to the workpiece, with about 85% of the power being concentrated in a millimeter-diameter beam. The 22 mm thick 1015 carbon steel butt joint of the guide rail was previously welded with a submerged arc welding. Each weld seam needs to be welded on the front surface with seven additional welds behind the shovel, thus requiring time-consuming work. Switch to laser welding after each seam
