Laser cutting (for metals) (fr: Découpe laser – pour métaux): A technology that uses a high-power laser to cut metal. The laser beam is redirected at the material (most commonly through optics), which then either melts, burns, vaporizes, or is blown away by a jet of gas. The result is an edge with a high-quality surface finish. Industrial laser cutters are used to cut flat-sheet metals as well as structural and pipe/tube shaped metals. Laser cutting has some advantages over plasma cutting – it’s more precise and requires less energy when cutting sheet metal. However, plasma can cut through greater metal thickness than most industrial lasers.
