日本三菱重工公司开发出一种利用激光焊接不锈钢板的新技术。该公司成功地用碘激光以每分钟1.2m的速度焊接10mm的不锈钢板。碘激光器产生波长为1mm功率为8.5kW的光。采用这种方法焊接不锈钢板,焊接速度要比电弧快3倍以上。另外,由于碘激光的波长大大短于二氧化碳激光的10.6mm的 Mitsubishi Heavy Industries, Japan has developed a laser welding stainless steel plate using the new technology. The company successfully welded a 10mm stainless steel plate with iodine laser at a rate of 1.2m per minute. The iodine laser produces light with a wavelength of 1 mm and a power of 8.5 kW. Using this method of welding stainless steel plate, the welding speed is more than 3 times faster than the arc. In addition, since the wavelength of the iodine laser is much shorter than the 10.6 mm of the carbon dioxide laser
